I have dedicated a few paragraphs of the blog post to this matter.
So in short I would need to figure out the aspects of modding on Linux, and write an "assembler" program for that too (Unix' ELF executable format is pretty different from Windows' EXE).
Based on my experience with Wasteland Kings modding, there will also likely be synchronization issues with cross-platform play due to runtimes working slightly differently on each platform. This part, fortunately, will likely be resolved by future updates of software used.
So overall, for the time being I'm working on having the mod work nicely enough with Wine. Which it largely does, aside of systems-specific slowdowns on loading screens.
