Absolutely not, hell no.
Bethesda would absolutely FUCK the original 2 games’ charm and appeal. I used to think a 3D Fallout 1 and 2 would be cool in the Fallout 4 Engine, but then I played the originals and if it were ported as a FPS it would completely ruin the balance of the game.
If they were to do anything, they should just Remaster the game. Update the graphics to the style of Wasteland 3 or Disco Elysium, while also fixing the game breaking bugs that can occur. And mayyyybeeeee finish the Thief Guild quest line in Fallout 1 and add the vegetation center back in Fallout 2. But other than that absolutely not.
