The MCMG were in ROH back in February, facing the Kings of Wrestling, which ended with a DQ run-in.
It was later explained that TNA strongly requested their team not take the loss (and didn't make this clear until late on.) ROH didn't want their team to lose, so the DQ finish. ROH probably isn't up for doing it again, but who wins and loses doesn't matter as much on a random indy show.
Realistically I guess this would happen with me too LoL - but if I could have either of them, it would be Trish in a sec. Lillian is attractive no doubt, but she couldn't pull off a half-naked, greased up bikini body like Trish can.
