Exactly, and I think Oda realises the potential disaster of Sugar's power now. If he's smart, he'll tuck her away at a corner and never let her powers surface again.

Seriously though, as interesting as the outcome of using Sugar's powers against someone major like Doffy would be, I highly doubt Oda will do that, simply because it's gonna be waaaaaaaaaay too troublesome to write the story if that happened. There would be literally a ton of repercussions Oda will have to address. The entire Dressrossa itself will be confused as hell. Just thinking about the things that will have to be addressed in such an event makes me feel that Oda should logically not want to even tread that path.
