I don't know where I saw it but I seem to remember the Raven Queen being a thing way back in 2e or even earlier. I know I'd heard of her many years before 4e was even a blip on the radar.
As for Primordials - OK, the name changed for 4e but the idea of deity-level primordial or elemental creatures goes back, again, to 2e if not earlier.
Ditto Archons - they were redefined for 4e as elemental soldiers (which makes no sense to me whatsoever!). Far better they be divine minions or angel-equivalents from various pantheons.
Well 1e-2e-3e Greyhawk had Wee Jas who is basically Raven Queen.
The Elemental Princes of Evil are from 1e, originally Fiend Folio.
