I don't think two beavers would be particularly well received, especially as DLC. There are several popular franchises like Rugrats, Danny Phantom, Hey Arnold, Jimmy Neutron, hell even Zim, that only have one rep. Beavers getting two full-priced characters, right off the bat, especially since both are 90's, would be a very controvesial decision. I know you love the Beavers and want to see them recreated faithfully, and I know they're doing well on the polls. But I don't think two full-priced DLC slots going to them would sit well with a lot of people. People want the remaining two turtles, but much of it is because their favorite turtle is left out, or because it just feels weird to have just two. The beavers are honestly in a very weird spot.
