Simisage as an Angel? Okay.
I want to see a Normal/Ghost type, a Dragon/Fairy, and an Normal/Dragon.
As for new types, before gen 6 I wanted to see a Light type or something, but I guess fairy fits that description fairly well. Pokemon that would have been Light type would have been:
Ninetales, Meowth, Persian, Porygon, Mew, Meganium, Togepi, Togetic, Ampharos, Dunsparce, Porygon2, Lunatone, Solrock, Milotic, Castform, Kecleon, Jirachi, Togekiss, PorygonZ, Cresselia, Arceus (Light forme) Victini, and Cinccino. Helioptile, Heliolisk, Amaura, Aurorus, and Xerneas would also have fit the idea I guess.
