Oh I dunno, years ago I had a transformable Veritech that I had to put together from a model kit. Admittedly the Veritech is a rather basic transforming figure, but it was still a nice little model kit.

At the very least i'd love to see Hasbro put out weapon/add-on packs. Mini-Cons were one thing but to really make your bots unique these packs would do the trick.

Body kits for Alt's/BT's would have been a wonderful thing.

But anyway, Gundam-esque model kits? I'd love to see them and I don't see why they couldn't be done. And given the rise in popularity of kitbashing/repainting over the last few years I wouldn't be surprised to see them try it down the track.
