Are there any qaf and perks of being a wallflower crossovers out there?

[maxwell-km.livejournal.com]

I recently watched the perks of being a wallflower movie and fell in love with it (mostly b/c of the music)- then I downloaded the book to listen to while driving and I really enjoyed it. But I started thinking that Perks takes place in Pittsburg in 1991-92, when Patrick, the gay character, is 18. Doing a little quick math, that makes Patrick 3 years younger than Brian. I know perks doesn't have the same fandom as qaf, but I was wondering if anyone knew of any fics where the characters from perks interact with the liberty gang or vice versa.
Thanks for any help!
None found- but still looking
