if things are going well just like until now, and I can achieve some improvements, if someone is interested, I can send a small package for trying/testing it.
(MapBuilder is needed, just the exe should be overwritten, and by some tricky hot keys everything is accessible. And I should finish my really low poly animated character with LODs for better performance, to replace the current infantry character got from a game.)
