I'm not much into details, but as far as I know, Steam has a list of games that work on Linux with help of Proton (their own version of Wine). Maybe digging in that direction will help to get your projects on the Linux market as well (if your projects work with Wine, they should work with Proton too, so maybe there is a way for you to get 'support' label at your projects). I guess this solution is more realistic that Conitec doing anything to gamestudio.

Best regards.
