yeah clone wars era Republic conjures scenes of the ARC, LAAT, and Z-95. Everything else is pretty obscure. even the Republic Y-wings are more of a lore thing, we hardly see them in any of the media.
Personally i think the only reason they werent included in the Republic faction to start is that FFG didnt want players starting out with full squadrons already in their collections.
I'd love to see Republic Zs have a uniquely easy dial with 6 or 7 greens, or maybe a unique configuration that gave them a segnors loop... just something to make them stand out from the other Z95s while keeping their role as chaff ships.
