Theoretically, she can still redesign the characters even if she is not on the "Phineas and Ferb Fanon Team". She just can't update the wiki logo (I think...? I've never attempted, for obvious reasons, except on the wiki I used to own) or .css.

And of course, she needs to have consent to redesign these characters. If the people who own the characters give permish, she technically can do this.
