As a main dancer, I know many many dancers have thought of this and wanted this type of thing for awhile. I think it would be an amazing idea to give us dancers a dancing waltz or jig that can support our parties or random outside adventurers with a Raise.
I mean, come on we can heal up to great numbers in HP even erase debuffs. But how many times have you come across someone who died and felt completely useless because you couldn't do anything about it? I know I have. Even if it's raise 1, I think it would be nice to throw in a new dance animation to raise the unfortunate. A Dispel flourish would be nice to :P just sayin'.
