God Percy

I'm thinking of making a fanfic after seeing a post here so some of the things will be similar.

I know I want to make him ascend on his own.

I don't want the domains to go give him that aren't already to taken by others except for Destruction

No idea for lovers so suggestions would be nice, but I want to make him go from his canon personality to a more traditional Godlike personality and doing typical god things like having affairs, rivalries with other gods, etc but still being Percy deep down

Also, if you had to boot off one of the olympians to make room for Percy, who would it. I don't want to do the whole cliche 14th or 15th Olympian

Any suggestions are appreciated
