Disney Heroes is at least one theme. There's always Adam from Beauty & the Beast. And someone suggested Flynn Rider, he works too. There's also Naveen and General Shang, etc. I'm just going off Disney Princess heroines, but there's more than a handful to pick from. and they don't have to be dudes obviously lol~

Since you're willing to change Cara's base character you could also make the theme "thieves". You've already got Aladdin, Flynn Rider's another theif, then maybe Robin Hood (although I'm sure that's pretty common), and...Jafar? You could also use some thieves from history like Jesse James, Sundance kid, Bonnie & Clyde, etc. There are a lot you could use in that department.

If you ever decided that you wanted to change Viola's, then you could go the other route and use Greek Heroes for inspiration. You could change Viola's base character to Hermes/Mercury. And there are a whole bunch of other base characters you can use for inspiration as far as greek hero/ines are concerned.
