Hi Garrison, This is a new one for me - normally we always balance everything when dealing with paralleled conductors. NEC 310.10(H) talks about conductors in parallel and I can't see anything the explicitly forbids what you explained. To be safe, I think it is worth contacting the PE to double check that they were aware that there are three sets of parallel conductors on each phase.
