I have an idea.Why not to create some advanced version of flatificator program to terraformer, which will try to recreate chunk,where it is placed?Not into original state with ores,etc - but with only cobble,dirt,sand,water,saplings,etc? I pretty much hate holes from creepers,lame mining,carriers,nukes,reactors and stuff like this.EU usage would depend on biome type.as from recepie..if it will go as a program,1 coble,1 dirt, 1 sand 1 seed and blueprint looks nice.
I think,something like that is really needed.
