@philip.ed: If you are successful, i would love to know how to do that myself 
After reading lots and lots (and lots) of posts, i developed this method for modding HSFX:
I put all add-on planes and cockpits in the "MODS" folder, all new sounds on the files folder and for all other mods i put them in "jsgmemods" that way i can activate/deactivate them as needed and also test for compatibility.
Also, in the mods folder i set the upgrades using the method of adding a "0" in front, in example, i merged all the skyrider files (cockpit and plane) together, but that made IL2+HSFX crash, so i separated them in "0_Skyrider" and "1_Skyrider" (first one for the plane, second for the cockpit) and it works just fine now.
