So I've seen a couple lists like this lately and made my take on it. Here's the list to start with.

Tank 4

Faction: Rebel Alliance
Points: 399/400

Commander: Garm Bel Iblis

Assault Objective: Advanced Gunnery
Defense Objective: Contested Outpost
Navigation Objective: Salvage Run

[ flagship ] MC80 Assault Cruiser (114 points)
- Garm Bel Iblis ( 25 points)
- Engineering Captain ( 6 points)
- Engine Techs ( 8 points)
- Advanced Projectors ( 6 points)
- Reinforced Blast Doors ( 5 points)
- X17 Turbolasers ( 6 points)
- High-Capacity Ion Turbines ( 8 points)
= 178 total ship cost

Modified Pelta-class Assault Ship (56 points)
- Raymus Antilles ( 7 points)
- Projection Experts ( 6 points)
- Shields to Maximum! ( 6 points)
= 75 total ship cost

Modified Pelta-class Assault Ship (56 points)
- Ahsoka Tano ( 2 points)
- Projection Experts ( 6 points)
- Assault Proton Torpedoes ( 5 points)
= 69 total ship cost

Nebulon-B Support Refit (51 points)
- Redemption ( 8 points)
- Walex Blissex ( 5 points)
- Projection Experts ( 6 points)
- Turbolaser Reroute Circuits ( 7 points)
= 77 total ship cost

Features

- can transfer 7 shields a turn between STM and projection experts.

- mc80 gets 8 engineering with command and token, which due to garm and ahsoko can occur every turn of the game if needed.

- neb b (which slow rolls in) can trc multiple times and burn the evade all it wants since it can get it back with Walex

My friends thought it was crazy but it's been fun through 2 games and a couple variations so far. First game my opponent poured everything he had into trying to kill the mc80 (I rushed forward with it at speed 3/engine tech's, while the rest of the fleet slowly moved up in support) and it took around 40 damage by the end of the game when it ended with shields close to max again and only a couple points of hull damage. Tabled that buddy (his list consisted of 2 arcs, 2 gozantis, an interdictor and 4-5 fighters).

Second game against a different friend I'd swapped out the engine techs on the mc80 for engineering teams trying to push even more heals and regretted that. He'd learned to ignore the mc80 completely and try to kill the support ships. Managed to kill 2 and I lost a very narrow 6-5 blockade run (which I played just cause I wanted to try blockade run)

Yes there's no squadrons. Against a list with a heavy bomber wing no idea how it would work yet but versus roughly 70 points they didn't bother me at all. Need to try it against a heavy fire power ship like an ISD as well so that's what's up next.

I'm very happy with advanced gunnery and contested outpost as objectives. Salvage run- well I havent played that one yet so it's in for now. Obviously would do better with strategic but versus most lists the mc80 should be able to get near the tokens and be enough area denial to hopefully get the others for the point boost.

Any feedback would be greatly appreciated!
