Carmack himself toyed with HD sprites for Doom on iOS, he even went as far as to have artists do a couple frames as a test. Turned out it didn't look great and didn't really add anything for what would have ended up being a lot of work.

And if you look at the retouched sprites in Doom 2 RPG, you can thank your lucky stars id never did a whole sprite set like that, because they look silly as hell.
