That's not really an option with Mir, unless you want to create a different launch vehicle to get it to 200-250km, but the Proton that comes with the Soviet Pack won't lift Mir components any higher than ~85km before it runs out of fuel. - Does anyone know whether it's possible to easily scale down the radial MJ component that comes with MJ2? I am looking for something I can stick on probes, so about 1/4 of the size of the current MJ module.
