gimmick? Erm, transforming toys....? sorry jk.
In all honesty, I personally think there's nothing yamato can emulate takara/hasbro.
As for electronic gimmick, like lights and sound and such, I feel that it will make the toy feel cheap. For the fold booster is different though, because it tries to recreate the anime. And please, no sound effect!
That said, the only light gimmick I wish for is for the head, landing lights and the wingtip strobes, just like a real airplane. Unrealistic, I know, due the wiring involved which will affect it's transformation.
Transformers=Function follow form
Macross= Form follow function.
