Could a force bubble in WW's skin tear her skin?
Are her insides made of less durable material?
If the answer is no to both questions, then I don't see an internal bubble doing anything to Diana.
Pointy forcefields...?
Sue is starting out already invisible and with shields up. That takes a lot of power, especially the shields. Does she still have enough energy reserve to launch an effective strike? IMO, no. I just don't see her as overall that powerful. I could see her maintaining shields perhaps for a stalemate, OR, dropping shields to deal an effective blow. But considering that she's up against a Superman-class being, I'm sorry, I don't see her winning in this fight.
