Cheyenne Jewel also does both in (different) films--fighting and porn.
She's literally done everything from the most hardcore stuff like facialabuse to ultimatesurrender.
Suitefights actually had two pornstars in catfights. Nadia White and Aubrey Black. Not vs each other but a catfight between the two would be interesting.
Aubrey Black was supposed to fight Vivian Fox but Vivian backed out of it. After seeing Aubrey's match against the experienced Brooke and giving her all she could handle, I think she would've wiped the floor with Vivian. Probably a beatdown type match the likes of Lexi vs Victoria

Jackie Hoff fought as Taylor at SuiteFights and she's a well known porn star.
Davina Winter is now a hardcore porn star and she fought for Tilly against Alexa and Dolce.
Jewell Marceau is another that has done catfights and competitive wrestling matches.
Probably the most known European porn star that catfights now (at fighting-dolls) would be Stacy Silver who's simply known as Donna at FD.
