I've never heards of rams and the peaceful gourami species being a bad mix...they pretty much stay out of each others way.
Pearls or honeys should be fine if you still want some gouramis.
My Dwarf Gourami and GBR had problems when the first met. The Gourami use to chase him. Now they get along ok. I still see some following and soft nudging now and again. But neither is scared of the other. BTW, my Angel, Gourami, and 2 GBRs all do this now. Subtle reminder that they are mean.
