For the regulars the standard 1790 French infantry, artillery and dragoons in bicorne should be sufficient I would have thought.
The light infantry and militia are a different kettle of fish, I once had a 15mm 1798 Maltese army and had the lights especially made by Irregular. For militia I was going to use Lancashire Games Vendean militia in head scarfs but never got that far before I sold it. I've no idea how to go about those in 28mm.
I do have several prints of the various units and re-enactment photos on my pc, too many to attach here, I can pm you them?
