Men of Gold and Red

Im re-reading Era 2 and looking more into the "men of gold and red" mentioned by Miles in Alloy of Law and again a few times in Lost Metal. I went down a bit of a rabbit hole on the Coppermind wiki and I'm not sure if this has been pitched yet

What if theyre enlightened reachers? Golden skin and statuesque, the reachers fit that to a tee. The red eyes says to me they might have been touched by Sjah-anat. Yes, theyre on Scadrial, yes its implied they're physically going to invade, but we know that Autonomy and Odium have some sort of truce between them, and from the end of Wind and Truth with Sigzil, we know its feasible to leave Roshar via the Cognitive Realm. We also know that there have been attempts made to bring spren fully into the Physical realm by Ishar.

Rambling aside, what if Autonomy and Odium are working together, took the scraps of a crazed man's research, and sent the spren who are noted to like freedom (Autonomy, anyone?) and hate Rosharan humans, to take over Scadrial. Better yet, what if instead of physically invading the plan was for them to act like the Voidspren with Venli and manipulate powerful people into doing their bidding?

I know theres flaws, but I think theres something here to be considered
