About a new map?

They current map is flawed, no doubt about it. The world painter terrain is just way too smooth. If I were to create a new map, of reasonable size and quality, would it be accepted or is the amount of hassle required to make the transition too great. I use a unique blend of 3rd party software such as MC-edit and World painter to make a basic shape of the terrain, then I add variation with worldedit and voxel sniper. Results are awesome worlds. I only do terrain though. Keep that in mind

I'm making this map (proves my skill):
