A crossover is an episode of one show featuring a character of another show, which both are somehow related by directors / creators / production company.
In your case, it would be MomPOV and GDP. I cannot see any 30yo+ in GDP, even in a 3way, but I could easily see a 3way with a new or returning MomPOV teaming with a previous GDP. That would be a crossover.
If the GDP girl is more than 22yo because it's been years then it's not a pb. If she's a mom, it's even better. If she's not into girls it would be tougher, like Shawna-Memphis. As long as she's been published or about to get published in GDP, and is not an established mainstream pornstar as you said, this is good. I don't see any competition with GDP, and I also assume your 3way with Amber and Jamie was a success. A mother/daughter is impossible as MomPOV is not about role play, it would be more of a younger-older GG with you in the middle for a real BGG. The interview part could be interesting too. I also assume you'd be able to access GDP resource pool to contact candidates.
But as you said "I most likely wouldn't go to any of the past GDP models", so there would be NO crossover there, and not a new idea either as you already did old-young BGG already.
