Sorry for my late reply, your post got lost in the mass of things. In theory yes, and I think I know how to go about it. However the problem is it requires editing of the startpos. Startpos tends to break mod compitability, but more important for me is I can't export any modded edits into a startpos file. Why? Assembly Kit Bob (a dev tool), is in this respect broken on Linux, you can export everything else with it, but not startpos. Thus I cannot make it even if I wanted to, say as an submod to this mod or similar.
