That certainly sounds like an interesting proposal. So if I'm reading this right, she'd basically have a very limited moveset whenever she transforms and each form would give her access to a different B special? I'm supposing those specials are cut off from her in genie mode as well as opposed to being replaced with something else, right? (Like, you could only use her Side B if you were in Elephant form, etc.)
Hmm... That could end up making her a really difficult character to use but it does sound pretty unique. I will say though, I really like

's proposal quite a bit. Could be pretty strange in that case to see her shining yellow as she dances though. xD
On the flipside, using the dance in place of the charge-up for her smash attacks could give her a unique meta in that you wouldn't know which smash is coming until it's released.
