She'd be more likely to leave Phase and end up indie than to join Holo. Phase is already restrictive enough on things she'd like to say and content she'd like to make. Holo would be hell for her. She's said before the reason she's in Phase is for the support from the people in the company. If she can get that kind of support from elsewhere (like her circle of indie friends she collabs with more often than the other girls inside her own company) without the drawback of having her IP owned by someone else, who knows, maybe she'd go down that route. There's no chance in hell she'd fit in at Holo, though, as much as she's a fan. Holo wouldn't want to be associated with Pippa's spicier side, and Pippa's fans woldn't want her to hold it back, either. She's already had to bite her tongue enough as-is in Phase. Nobody would benefit from this course of action, not Pippa, not either of the corpos, and not the fans.
