at the end of story after you finish it allow an optional choice since you have no soul that molag bal or even that femal daedra that helps you in coldharbor a choice to become daedric and have a class line similar to vampire. Of course you'd have to start a completely new character and go through game all over but I'm betting that there are enough people out there to do this.
As for race I'd like to have chance play as a sea elf and have a sea elf motif in game (looks can be geared towards a buccaneer/ pirate look).
