2 Possible B/Y lists I was looking at.
2 Gold Squad with Ion (no title)
2 Daggers with Adv. Sensors / Accuracy Corrector / or FCS
2 Gray Squad with Ion and a 1 pt droid (no title)
2 Daggers
I prefer the second just because of choice of which ship to move and shoot with first. I'm actually thinking R5 astro for two reasons. Using a turret means k-turns are less important than if I was running BTL-A4 and R5 could get rid of some more annoying crits but sadly does nothing for the most critical hit to the Y (munitions failure). Direct Hit, Console Fire, Minor Hull Breach, Damaged Engine, Structural Damage, Weapon Mod, Damaged Sensor Array can all be flipped down for no action. Maybe it's not good enough but between the two options at 1 point, it seems slightly better to me. R2 Astro could still be very useful, though. Being able to start with a straight 4 and then take a 2 speed maneuver could be a powerful jousting start if I'm in a matchup where I want to be aggressive.
Ion seems like a good thing to have right now but I don't know if the 4 thugs/golds has enough firepower, so was thinking maybe take 2 Bs along with 2 Ys so there's some actual fire power and still have some control elements. I'm actually not looking to take the BTL-A4 title because it limits where your ion can effectively be used. You could set up an arc and Soontir or Corran or even Dash or Jake pops up behind you when he was in front of you the round before. B-wings just do what B-wings do. Lots of hit points all around, as well.
The ships most used in meta all have some weakness and strength against it.
Brobots - If they stay maneuvering well, I may not get the B-Wings on them consistently. Really have to work for an ionized target and then work to keep it ionized. 3 Agility + thrusters makes this a hard fight but the firepower of the B-Wings when they do have their target should be quite useful. Hard to keep ionized, though. Ionization extra useful against those that run Adv. Sensors.
Corran - Firepower of the Bs might be enough to bring him down. Could also get a lucky position with the ICTs. Arc-dodging is annoying and usually run with something else that is often the bigger target.
Dash - HLC can take down any of my ships in two unlucky shots. I think if this shows up in a list,it's my priority target. Wear it down and take pot shots at it's escorts. Ion kills PTL Dash, so that's a boon for ICT. Some of the less run Dash builds will be annoying to deal with.
Soontir - Have to play smart and take best shots I can at him. One of the harder matchups, have to force bad decisions if possible.
RAC - This is actually one of the easier matchups. Take TLs and Ion him off the board. Until he's without shields, there's no chance of him avoiding as long as I don't whiff four times (one for each Y, one for each TL).
Biggs - Haven't seen him much in local meta but I see he's popping up in regionals. B-Wings should make short work and Ionizing him could break or slow their formation.
Han - Possibly a trouble ship but easy to ionize Han, though C3P0+MF interaction might make it fully ionized every other turn. Four ships worth of shooting should make that less of an issue. Fire with b-wings first to strip the evade.
Chewie - Pretty similar to deal with as Han.
Double YTs - Target priority can be hard in these matchups. If 2400 + 1300, probably the 1300 first.
Z95s - These show up usually as escorts for Han. Need to minimize how many fire at one of my ships each turn but my focus will likely be on whatever they're escorting more.
Double Decimator - Usually one with Vader, probably a good thing to clean up first. I'm unsure of whether that's necessarily true... but less hit points means less fuel for Vader.
Old Man - This is not a fun matchup, but ionizing one of the Bs gets their formation screwed up. Since I'm PS4 on at least half my ships, then I get to put some damage and even potentially remove one during joust. This list doesn't seem to show up as much but it could be a nuisance.
Boba Fett - Being run alongside Aggressors in some regionals. Hard matchup actually, especially against the Tactician build. Facing that, you don't want to be range 1 or 2 of the Fett and you don't control the engagement. Think you just have to hope for the best in that matchup, and probably go for Fett first because of the additional 2 HP and possible control elements. Without Tactician, not so upset being at Range 2. B-Wings still have to do extra work if we get up close.

So, is this a nonsense idea or possibly workable?
