I know this isn't quite what you wanted.... but FS2 retail breaks my pilot files

While you guys are tweaking pilot files... would there be any possibility of a file converter? I'd like to be able to, for example, play Inferno Ch.1 through to Mission 13 in FS2_Open, then play the last mission in retail so that I can see Earth. I'm sure there would be many, many other uses for this as well. I'd do it myself, but all my programming knowledge died with the Apple IIgs, thus forcing me to be content with testing.
Any ideas on if this is possible, feasible, etc? Thanks in advance.
