... I'd be enthusiastically open to that.

Wisp has no money (so she'd never think to go to such mercenaries), a distrusting personality that I put in her to ensure she didn't go to the Protectorate (so she'd never normally consider joining a team), a stranger power that she hides with (making it hard for others to find her in the first place), and if the other members of the team wants to do other things I wouldn't want to force something unnatural in order to make her come into contact with them, but yeah. I'd happily be open to that. Haha.
