Question to developers?
Could this become possible ( I realise still not entirely easy) if you try porting from the Mac code using GNUstep.org rather than from the Windows code and focusing on the lack of WPF. All discussions about this come down to a lack of WPF on linux. Wine will never be a solution for us - believe me I've tried to explore this and wasted plenty of time on it.
We need code compiled for linux and deployed using appimage so that it will work on all major distros.
