I would much prefer to see this "At the beginning of the Combat Phase, you may acquire a target lock." included as an upgrade card which is available to the Tie D and maybe the shuttle only. Make it the tractor beam. 6 or 7 pt upgrade.
Forgive me, but why would you make it a TIE/D-only upgrade and not simply a pilot ability for higher-PS pilots? It's the same difference, just one's an option, but that option doesn't fit in the spirit of the game with it being an upgrade exclusive to the TIE Defender but not available to other fighters.
