Yeah, I’m probably going to use the Universal magic route.
Okay, cool! Though, you'd still be attuned to one of the four elements, so feel free to toy around with that. And for the appearance altering part, you could always have that as a racial trait, similar to a Changeling or a Skrull.
Shit, I totally forgot about that option before. Racial abilities not tied to magic. So, as long as it's not too overpowered, everyone can feel free to add racial traits to their characters, such as wings, darkvision, heightened senses, form-shifting (such as lycanthropes), etc.
