Some really really cool ideas there, definitely some creative interesting stuff in the last paragraph particularly.
I'd mention though that the reason I was espousing the "more of the same, only bigger" concept, as well as the "just let us summon pretenders" concept, was to avoid arguments about design issues. Graphics aren't a problem with those more basic approaches, and balancing isn't SO hard when you are working with a formula that already works, just increasing some variables to plug it into a later position in the game.
Personally I'm all for really wacky, fun, distinctive summons, I just want to see things make it to the game, and preferably in an official capacity, as well.
Which reminds me, is Sombre's new avatar a prototype for a chupacabre?
