^thats only with the Cyclone Joker set, most of the sets that have alternate forms don't have such an extensive set of alternate parts, if they include them at all. Usually its just an alternate chest, and some swappable panels, not swapping entire limbs.

oh and here's a better shot of the head, looks so good imo:
there's also a painted photo of Kiwami Tamashii Kuuga up as well:
