I can't make any mod, but I'd like to get a mod with real parts like an air compressor that transforms intake air in oxidiser (with an IRSU-similar texture and design), that doesn't make much heat but a lot of noise, some rover cargo bays , long cargo bays and eventually some powerfull air breathing engines for a takeoff without any oxidiser use and big jet engines to use as VTOL hidden engines or engines integrated with a cargo bay.
