A cult for individuality of expression having to be exactly correct in a Latin phrase? Oxymoron of the year!
Cultus cuique singulorum reverentiae (Cult for reverence of individual things)?
My Latin is forty years out of practice and may be off on the individual things part. Latin isn't really a dead language, it's just hibernating or as a New Question asked about the other day, feigning death (Thanatosis, a Greek word! Have you thought of using Greek for your motto instead of Latin? That would certainly be an act of individuality). Use what your group is to be known for: individual concepts, and create a bit of Latin or Greek to your liking. Just watch out for the Latin Police when they come knocking on your portal.
