I think romanians have most overlap with south slavs and albanians and a bit less with hungarians,east slavs,west slavs,french,italians and greeks. Romanians have quite diverse looks, because of quite diverse ethnic origins of the people(the ethnic elements that took part in the ethnogenesis process I mean).

For Sicilian, I'd go with Maltese, Greek, and Cypriot.

For Portuguese, I'd go with Spanish.

Can mostly pass as Puerto Ricans: with exceptions of the obvious ones such as Cubans, Venezuelans, drs, etc I would have to say morrocan.
