I think he would have, yes. Any help against Morgoth was welcome, and the Sons of Feanor were tolerant and admiring in general of any men who fought Orcs.

One crucial thing to remember is that recruiting the Easterlings was by every code of morality, honour, and tolerance the just and right thing to do; and that it was rewarded by the loyalty of Bor's sons, at least, who are too often forgotten-Easterlings as heroic as any of the Edain-"...Ulwarth and Ulfast were slain by the sons of Bor, ere they themselves were slain."

"Ere they themselves were slain." Presumably their people with them. Think of the sacrifice that entails. They didn't have beautiful names or countenances, but they fell as valiantly as Hurin's folk at the Fen of Serech. They ought to be remembered with more honour. Who knows; perhaps even some of Uldor's men resisted their lord's treachery.

Even with hindsight, the acceptance of Easterling aid was a noble and correct act. And had it been rejected, defeat would have been equally inevitable. The numbers the Swarthy Men lent to the Union were surely vital.
