Serpent's Trench Map

[Blue Mage Gab]

I was thinking to use the Serpent Trench map for a third-overworld map as well, but isn't it possible just to change the Serpent tileset to the WoB or WoR tileset, who have all the effects applied(like, you can't walk on water, only a half of your body is visible inside the forest tiles etc.) and then build a brand-new map with the WoB/WoR tileset in the place the Serpent Trench map used to be?
