A89: Substitute Domain (CC, Cleric 2) is simplest. Few other options exist.
An even simpler option is the Adaptation section for RS; simply pick a better Outsider to mimic, or ask your DM.
Ones I'd go for would be sure to have Destiny, at least, and maybe Shadow. I'd consider Time/Planning/Spirit and others for the third.
Shadow/Transformation/Destiny is pretty sweet, no?
