Friend of a friend game?

I was thinking about social circle a little bit. While I have made some newer friends, I recalled this female friend (let's call her T) I used to talk to in high school (10 years ago). I liked her and I'm pretty sure she liked me, but we were both shy (especially me) and nothing ever happened. At the end of senior year, we were at a school-sponsored social event. We were sitting together, talking, and I put my hand on her back (she was somewhat receptive). I heard she was going to an after party with some friends including two other attractive girls. I asked if I could come and she said no, it was just going to be girls there.

We haven't stayed in touch, unfortunately, but T and I are Facebook friends. To describe these three girls, they were a bit artsy, slackers, not popular, bisexual. T has moved away in the years since high school, but the other two still live close to my area. I looked up both of the friends on Facebook. One of them has her relationship status as single; the other doesn't have a status but no boyfriend/girlfriend in her photos.

I was wondering what the best way to go about this would be. My instinct is to message my friend T and chat a little bit before asking her to introduce me to one (or both haha) of her friends. Any ideas?
