Think this could do well in a competitive environment if flown well?

Boba Fett:

Tactician

VI

Seismic Charge

EU

Glitterstim

Syndicate Thug X2:

TLT

Unhinged Astromech

Planning on fortressing boba behind Ys for the first few turns then letting him blast out for perfect range 1-2 shots on first engagement. Then he flies by and shoots out rear arc before turning around and coming in for another pass. The Ys are fairly mobile and can split to make sure ships can't be in both of their donut holes at the same time. Opponents can go after TLTs first and get pummeled by boba, or if they chase boba get hit by TLTs. Also forces them to choose to be at range 1 of boba and give him re-rolls, or range 2 and take stress.

Any tips or advice you all have would be greatly appreciated. I have limited ability to practice, so any game plans you have against specific common lists would also be appreciated. Thanks!

will do better as r4s instead of unhinged. The 3 turn is severely overrated and dice mods are life (seriously, r4s can punch damage through r2-d2 Poe; they're that good)

toss the seismic to free up the points

Short answer: yes. Not sure how I feel about the fortress setup--you really want Boba as a flanker. If the enemy gets some concentrated fire on him, he'll go down really quick.

Been practicing with aggromech. Really adds an extra punch. Thanks.
