I don't know, I have a friend, Guy, who still to this day calls 3e "that horrible WotC edition" and insists that they should have stuck to making a card game. The way he talks, you might think he was somehow personally betrayed by 3e's existence. He still plays and runs his 1e/2e mashup with tons of custom rules, and he seems barely cognizant that we're up to 5e D&D.
When you ask him what the big deal is, he always starts with "why did they change Thac0, there was no reason to do that". He actually likes rolling high to attack and rolling low for ability checks! He likes the random d100 subsystems- I've tried for two decades now to even get him to try a newer iteration of D&D (or even Pathfinder), and he turns up his nose like it's limburger!
So yeah, I don't think you could have seamlessly ported 5e to the 80's. People playing regular D&D would be like "uh, why is everything so complicated and weird?" Also, 5e has demons and devils and let's not forget how that went...
And come on, AD&D without Gygaxian hyperbole and purple prose? Without arcane and profound rules densely packed into the DMG?
Blasphemy! People would riot in the streets saying "where's mah rules, TSR?!"
