Implementing multiple mappers on a cart would be a difficult (or perhaps impossible) task. Only one mapper was used at a time on a cart as there was no need to be so insane. It is expected/recommended that the bitpack for an OHC specifies which expansion chip to use for an NSF+ compo, unless there is some other strong theme to keep the entries coherent.
