You'll need to be more precise. What are the things from the changelog in 1.07 that you want in SEE? "Base the mod of 1.07" is a very simple statement. All balance changes will be neglected because SEE makes changes to all factions and thus has to rebalance from scratch. Bug fixes will still get fixes as well as can be done, Naz won't leave bugs in there just for fun.
Regarding framerate, I don't understand what you're getting at. Does the vanilla game (ie, un-modded) game run worse than SEE and 1.07? Does 1.07 run better than vanilla? Does 1.07 run better than SEE? Does SEE run more smooth than vanilla?
I still cannot see what reason you have for wanting the mod to be based on 1.07. Are you aware of the amount of work it would take to change the "mod's base"? You can't buy a Ford and say that it's okay but you want it to be more like a Ferrari. Not without specifying exactly what you're referring to. You want a faster car? By which means? Bigger engine? Lighter weight? Better aerodynamics?
You seem to forget that SEE is, in reality, a total conversion of the vanilla BFME2. Community patches will not do it any good, with the exception for specific things that they improved upon for vanilla that SEE could use.
