You should consider having an export data open standard file format (like in json) or something that developers can use to load the map and add their own "enhancements" over it. The voronoi structure/neighbours, etc.
Though i think re-coding stuff to Unity asset would be better for Unity users as well, since it comes bundled with all the physics and such. Can try the C# export in haxe for the engine-agnostic codebase.
