That is an important point, that non-IP attractions can help draw in different audiences not attracted to your IP.
The larger problem here for Disney though is, the people that ARE attracted to their IP and want more of their brand, are generating far more demand than they need.
Eisner saw Disney as being capable of being all things to all people, and promoted the idea of having rides and attractions that weren't just themed to the movies or characters or studio content. That was the original thesis for California Adventure, that they could expand the brand by bringing more adult-oriented content as a counter to Disneyland. It didn't work. He was wrong. Disney isn't going to do that again.
