That's all correct, you're good to go.
Changing Aurora's file extension from .SP to .EXE, because apparently I can!

Justification: She has had experience fighting in a Navi's EXE container, both present and past. She'll still be a Support Program though.
I can't see any direct rules about it, so I'm going to approve until such a time as anyone else finds a ruling that says you can't ^.^
