I came at this a while back in a bit of a curveball solution: a Crew upgrade that deploys a couple of Academy Pilots for no cost as a escort, and which don't contribute to MOV.
Something like...
Captain Slavin
Crew - Imperial
At the beginning of the 'Place Forces' step you may add two Academy Pilot TIE Fighters to your squad, without paying their squad cost. At the end of the game these TIE Fighters do not count towards either player's MOV score.
6
What this solution does is thematically bring in that TIE Fighters are cheap (6pts for 2!) and the Empire doesn't care about them (no MOV risk), but by tying it into a Crew slot you're avoiding a lot of the risks that just reducing the points cost of the TIE would feed into huge swarms that just slow the game right down.
