I don't know if the OP's question is still on-topic, but I'll just answer it anyways..
I've actually seen a lot of guys with nostril piercings - not as many as women of course, but nose rings have been punk since the 80's. As long as you have any sort of facial hair I wouldn't worry about it affecting your passing at all.
I used to have a nose ring and long dreadlocks while pre-T, and they didn't make me pass any less than with no piercings and short hair.
