Daggerfall would never play and feel the same way if remaked, even if it's on a better, more stable engine than Daggerfall's bugginess.
Very, very few games that are remaked surpass or are as good as their predessors. Resident Evil 1's remake on the GameCube is a good remake, partly because of the voice acting that was.... a little bit better.
And the much better usage of graphics to redesign the scariness of the mansion.
Daggerfall can't be modernized. Modern games that must sell today need full voice acting. That's already cutting a lot a budget for a Daggerfall remake. Plus, it would "sound" weird. Since it is automatic, randomly generated responses that the NPCs give to you. Having a NPC say the location of a random dungeon in quest line would sound like when your voice mail tells you how many messages you have. "Please save my daughter. She's held in CASTLE NECROMANGHAN (Insert different intonation here). "
It'd sound like Operation Flashpoint, Arma or Freelancer. The voice acting is not bad, but the implementation is.
A modernized Daggerfall would still look, feel and play old by today's standards in videogames.
Like most movie remakes, they are never as good as the original.
