According to Wiktionary, the adjective paucus, although typically found in the plural, with a meaning typically pertaining to quantity, can mean:
1. few, little
Usually plural; very rare in the singular. Mostly pertaining to quantity.
The usage notes and the inclusion of little in the entry seem to imply that paucus can be used to denote something little, specifically concerning size, but I am extremely doubtful. Thus my question: can paucus be used as an adjective meaning little, specifically with concerns to size?
