Geoff Carter is an excellent and smart writer who, among other things, produces the Disney-centered blog YourSouvenirGuide (but don’t hold that against him). In the post Ten things Disney could have done to geek up without buying Marvel he explains both why Disney buying Spidey was a bad idea and how they could have leveraged the properties they already own.
My favorite suggestion:
9. The Disney Princesses: Teach them kung-fu and arm them with wrist-holstered blades and pistols.
Works for me.
