Changes to the Muses.

I'm thinking of making a few changes to the Muse storyline and am asking for all your opinions before I write my next Muse academy story which will have the changes.

First is the duties of the Muses, Dora and Melody only have one while the others have two, so I'm thinking of taking away history, dance and literature away from them so each of them only have one.

Dora's name, I'm unsure about this Muse's first name. When I first created the Muses I just made random names that I remembered, all of them have sat well with me but Dora. I got the name off of the kid's show because I thought it'd fit the childish personality I was going to write for her and it does, but I'm still unsure on the name.

Do the Muses need an enemy specifically for them, they're all powerful legacies of the gods so they'd need someone to battle against.

Should there be other legacies introduced? I've said before in the story that there would be other legacies out there for the other dead religions that had enough belief in them, like for the Egyption relegion. So what would it be like if these legacies interacted.
