The Mexican is real heavy handed and is capable of knocking out Gamboa. I'd expect Gamboa to win but this would be a good scalp for the Cuban and would get him the WBC also (assuming he wins his upcoming fight).
Cuban needs to be matched with Mexicans like PAC if he is gonna become a big star... That Gonzalez fight I never thought about, seem interesting.
I think Gamboa is better off just moving up to 130. The JML/Salido rematch keeps getting delayed and its not set in stone if it ever will happen. So theres no point waiting for JML. Waiting for Donaire is a pipe dream because the wait could take years. John is content fighting bums in his homeland. Move up to 130 to set up a move to 135. He'll be getting the money fights at 140 against guys like JMM, Rios, and Maidana in no time.
