Honestly no, I would rather not see any new areas added to the game for two reasons.
First of all I want to have an update not a remake. I cannot see the usefulness of adding more dungeons to the game as there would be no real story or item reward for doing so outside of adding more hours of gameplay. The mission of the game is fairly tight to begin with so I cannot see what an extra ice dungeon could add to the game, at least not without having to add an extra sage medallion or some other item to the game as a reward. If there is no point in going there most people would skip it entirely, ruining the effort in making it in the first place.
Second I think if more were to be added to the game it can easily be added to the areas you currently visit. There are too many places in OoT Hyrule which are only used once for maybe a single mission and all the NPC's within it are mostly pointless. Or just added to give it some population. The Goron and Zora villages were like this, 98% of the NPCs within are only three to show the players that Zora and Gorons live there, in a cave with one or two rooms only and a bunch of people that just wonder around aimlessly for no other reason. Even Castletown was a mostly empty place with little to do but cleverly disguised by a large city backdrop. I would much rather have more areas to visit and more places t explore within Castetown, Goron city or Zora Waterfall. Actually expand all these areas from a single room to a larger multi roomed environment with plenty more to see and do and more people within to interact with.
