Pretty much. Humans and duardin are mentioned A LOT as active factions in all AoS Mortal Realms, while Seraphon got just a couple of tiny references. And still we are fully supported, while on the other hand...
But.... the humans have stuff like big letters saying "Karl Franz" everywhere and so on. That's just.... no.
Only the generals do though. Just pretend they're all called Karl or are the biggest fans of a band name Karl Franz Plus, since the normal footsoldiers don't really have it they could at least salvage those. Mash it together with the duardin, aelves and the random wizard factions and I'm sure there's enough in there to have a decent-ish army. maybe introduce a new general or two but shouldn't be that much needed.
