Always super into Jojo's stuff, a few questions!

1 is it possible to use the Spin? I know we're going by up to Part 6 and I'm fine with it being a no, I just have a neat character concept in terms of a guy in a wheelchair who uses the Spin to do cool stuff.

2 Would a Stand User with the ability to 'possess' different shadows and turn them into constructs for different things work? It would only be able to possess one shadow at a given though it could switch between them rapidly and it wouldn't work if it was too dark for a shadow to be cast, but I feel like it could be cool for a lot of different effects and I like the idea of someone with that power who's like...kinda actually a nice guy rather than the expected 'super edgy' type XD
