How to detect if a player is using a body package in r15?

Is there anyway to detect if a player has a package on if the game is set to r15?

Say if they have 2.0, or the superhero package, I can change a certain value for them or something. It's easy to do this with r6, but I was wondering if there was a way to do it with r15 or not.
