Here are my suggestions.
Wind Temple from Wind Waker. (Probably going to have to alter a room or two due to a lack of Iron Boots)

Snowpeak Ruins from Twilight Princess.

Woodfall Temple from Majora's Mask.

Out of the 3 I suggested, I feel the Wind Temple might be the easiest to replicate since it isn't as visually "Taxing" as the other two and most of the Iron Boots Platforms could be replaced with Ice Hat Platforms, places where you need the Hookshot won't really hinder anyone since Hat Kid can Double Jump and wallrun, and as far as the areas where you need to ride the wind up with the Deku Leaf are concerned, Hat Kid is already affected by wind physics anyway. The only thing that would likely have to be changed are areas where you NEED the Iron Boots to not get pushed away by the Wind.

I suppose since your doing it anyway for LA, Color Dungeon

What about Inside Jabu-Jabu or Deku Tree ?

if you do gnarled root dungeon, then you get an excuse to look for another model for aquamentus.

if we're sticking with 2D Zelda dungeons...hmm...perhaps one of the dungeons from the Zelda Oracle games? Maybe Dancing Dragon Dungeon?

All child link dungeons from ocarina of time

it just makes sense
