Sounds good, especially that you are looking into the OD code too.
Currently there seem to be two ideas over at the OD board, either going along with Summoning Wars, and given some of the comments regarding the messy code of OD I guess that would mean trying to integrate the tile editing features into SumWars or such, or making a voxel based OD on the Lips of Suna engine. Personally I would much rather see the former, but the latter might result in some interesting ideas too.
So please keep up updated on what you opinion on that is.
