Novus - More Creatures

I am running Novus. I need more creatures/monsters. I have read around and seen that there is a Rolemaster and Harp link. How easy is it to convert between these systems? I could "reskin" what there already is in the handbook, but that doesn't leave me with a sense of deep satisfaction.



Alternatively, what other systems can I grab creatures from and quickly (eyeballing it!) use? Suggestions welcome.
