I don't think that needs to be what they are worried about. They need to start making solid attractions again and the rest will work itself out.
And if they really want to synergize in a "cool and relevant" way, they have Kimmel. Throw him in Atlantic Dance Hall for a week of shows and let him and Guillermo run around.
They can synergize too. They just need substance to make it worth the effort.
They wouldn't let Kimmel be himself. They'd basically tie a plaid noose around his neck and not let him make fun of the place. In case you haven't paid attention, Disney takes itself way too seriously.
