You could do that, or you could introduce them to... I dunno, Sekirei maybe? It's not exactly "fighting over a guy" but pretty close. Or Zero No Tsukaima... not a perfect fit either, but I've been too lax in following anime and manga for the past 7-8 years to think of anything really good. Ryoko would probably enjoy them if no one else, and if Mihoshi was into them as well it would be hilarious. Yeah, there's Ranma, but on the one hand it might hit a little TOO close, and on the other it's almost a decade since I concluded I was thoroughly burnt out on anything close to original flavor Ranma, so I don't want to promote it being included even as a throw-away gag - abusive relationships are anti-funny.
