>>2564029I may be a bit out of my depth here (not sure if any of these are already in or if you don't/can't do VV suits) so apologies in advance, but I'll suggest a few.
Dark Prison
Yogisari
Noctiluca
The skimpy Scarlet/Venus jeweled suits. Don't know what they're called, but they're reminiscent of the Fortune suit.
Whatever picrel is
And of course, cross-girl compatibility between the existing suits
