Superman and WWH are about on par--though Superman needs at least a somewhat dynamic power showing to hold his own.
I think WWH would beat Wonder Woman. But it would be a tough fight.
So two WWH are probably favored here, ignoring teamwork possibilities. At best for DC, two WWH is even. Three is definitely one too many. Four is overkill and it wouldn't take long for the DC Duo to get pummeled if they stood and fought.
DC's only hope would be an extreme power showing by Superman and a lack of a similar dynamic, power boosting response in the Hulks. When you have dynamic characters, anything is possible. But seriously, Hulks smash.
Stacking fodder won't help. 4 WWHulks, groundbound, slow compared to Supes and WW, far less skilled than WW. Superman should be stronger than 1-2 Hulks, the current one, and WW without the bracers would be stronger too. I don't see how the Hulks can win even 1 out of 10 fights in a Forum fight. You would need a lot of PIS and CIS from comics to give them a chance.
