I doubt this list, with its low-ish pilot skills and reliance on gimmickery, will have much success, but it's a bit of fun jank that should be able to cause some trouble in casual games:

Leevan Tenza (25)
Wired (1)
Renegade Refit (-2)
R7-T1 (3)
Integrated Astromech (0)
Servomotor S-Foils (0)

"Hobbie" Klivian (25)
Renegade Refit (-2)
Targeting Astromech (2)
Integrated Astromech (0)
Servomotor S-Foils (0)

Tarn Mison (23)
Renegade Refit (-2)
M9-G8 (3)
Integrated Astromech (0)
Servomotor S-Foils (0)

Ezra Bridger (Sheathipede) (17)
Snap Shot (2)
Hera Syndulla (1)
R3-A2 (2)
Hull Upgrade (3)

Total: 100

Each of the X-Wings is designed to play with target locks in its own way. Leevan Tenza loves moving fast; with her droid-enabled boosts, she can acquire target locks AND gain evade tokens, while also triggering Wired to keep her a bit more alive. Hobbie gains two more red maneuvers (the Talon Rolls) to proc his Targeting Astromech, letting him remain remarkably mobile across the battlefield. Tarn Mison can help out friendly forces with a minor offensive reroll (before their own locks come into play), all while giving himself some defensive boosts. And Ezra? He's just there to be a nuissance. The Hull Upgrade could be swapped out for any other passive modification (like Multi-Spectral Camouflage, Pulsed Ray Shield, or Stealth Device), since he expected to be stressed to the limit most of the game.

Observation: Wired gives you rerolls. Since R7-T1 is handing you a target lock which gives you unlimited attack rerolls, all wired is giving you is rerolls of green focus results, which....frankly aren't very good, since the rerolled die has only a 3/8 chance of coming up useful. It is free, I guess, but I'd find myself wondering if you could find the point for Intensity, instead. That gets you an all-up focus token for focus/locked attacks (and his pilot ability generates an evade to 'pay back' intensity) or else lets you double-evade or evade/focus if you expect to get battered.

Yeah....he's really, really good now. Being able to pull a white talon roll and come out of the turn with target lock and focus is scary good for only 25 points.

Given that both other X-wing pilots can generate more rerolls than they know what to do with.....what is M9-G8 doing here? Neither of the other pilots really need him for a passive boost, and if you're just trying to make Tarn irritatingly tough (not a bad thing to do) then R7 Astromech does the same job, arguably better, for a point less.

It's Ezra, flinging stress like he's a chimp with a bucket of faeces. Hera does let him use his full dial, but if you're not bothered about clearing the stress, his white dial is probably good enough - in which case I might suggest Baze Malbus might be a good idea, letting you fling even more poo per time interval. You can pay for the bearded dakka dispenser by dropping the hull upgrade to multispectral camo; you're never going to make a sheathipede 'tough' per say, and a 6 hit target isn't detectably harder to kill than 5, so much as just making it a massively unappealing target - unlimited defensive focus combined with the possibility of any harpoon missile lock evaporating before you actually get to press 'fire' does that as well as anything.

I like some of those ideas. Like you said, Hobbie is loving his new red maneuvers. Giving Tarn the R7 frees up the point for Leevan to get Intensity, which reduces redundancy and helps with even more tokens. As for Ezra, the only reason I still favor Hera is the ability to pull off any maneuvers I want, to keep his Snap Shot in aimed at the right places. People sometimes forget about Ezra pulling a K-Turn when stressed, for example. That said, Baze does give him a lot more utility in the early game, letting him dump off stress as many as three times in a round. That can lock down Reapers from being able to Jam my X-Wings, and prevent other ships from arc-dodging my relatively low PS ships in the first confontations.

Here's my thing: I don't like Hull Upgrade in general. I guess it might not be too bad on Ezra, but still, I tend to find it a pretty expensive upgrade.

I'm kind of inclined to swap out Leevan (I've never really had much long-run success with R7-T1), drop the hull upgrade, and grab a more expensive X-Wing as the 4th ship. VI Wedge Antillies or Wes Jansen are both 28 points, and could be fairly strong in the list. Wes loves when there are lots of other ships shooting at his target. Mostly, I've just never found R7-T1 to be that good on the table. Flight Assist Astromech allows an X-Wing to move pretty fast out of combat, or BB-8 gives a lot of low-speed agility.

I know I'm just going to contradict everything there, but how would dropping Hull Upgrade for Luke with VI and R7-T1 work? T1 works a lot better on high PS ships, and Luke is PS 10. His defensive ability isn't quite as strong as Leevan's, but it also doesn't leave him stressed, and opens up all the white and red moves of his dial.

I do kinda like M9-G8, however. I feel like giving Ezra a reroll (which works on his Snap Shot attacks, too!) probably goes a long way, and it would also be great if you went with something like a VI Wedge or Wes.

One last thought: perhaps Jek Porkins. He can be kitted out with VI/FAA for the same cost as Leevan (so you could keep the Hull Upgrade), and like Hobbie he's good at taking a red move and ending up without stress. With an M9-G8 reroll and a focus of his own, you'd have two double-modded ships after K-Turns.
