I would make it a mission to hook up with her, buy her a wig, some fancy dress, pick her up at a bar and rent a hotel room. Hell you can even use fake names if you want too. The thought of you being with someone else might turn her on, but the reality of such is very different. There's std's to think of, you could get some chick pregnant, she could turn into a stalker, be crazy, steal your wallet, any number of things. Like lulu said, risking 10 years for a random shag is not even worth it.
You stand to lose so much more than you would gain.
