Pete / Patrick is Peterick. I'm sure it's still going strong. Pax Am Days came out recently, they did a whole bunch of festivals and going back to the source of this they came back. People would get ideas from all this stuff; go ahead!
Also, question. Was it hard to write your blind story? I attempted one just last month, and it was difficult. Did you do any preparation? I blindfolded myself for an hour and ate dinner, fed the cats and got ready for swimming.
A lot of people read Fall Out Boy fan fiction still and Peterick is a pretty popular pairing. Even if it doesn't seem like a lot of people write it, I say you should still go for it.
