I will put acrylics over an enamel primer coat, but not the other way around. Probably just the styrene junkie in me (shhh! don't tell anyone!)
I would take into account the consequence of the paint failing, even if the probability is low. If the painted area is accessible and resanding and repainting would be relatively easy then it's worth the risk. If not, go carefully and use paints known to be compatible and, to be even more careful, do a test piece. Fair winds!
