UnofficialPatchPlus(UP) 11.5 and 9.2(or CQM) - differencies

Well, sort of. I have already warned both you and Bürgermeister about my idea of combining both mods in my submod for CQM about 20 days ago, though I have not yet even decided whether it will be a public submod, not to mention what exactly will be moved from UP 11.5.
I must be honest these 20 days were nightmarish ones, since I have no experience of modding at all(you can find my question about doors here, which now looks like a totaly noobish one) and I was experimenting, trying to figure out what I can do and what not. So many engine limitations and bugs I have found in the process, not to mention the cost of every my own silly mistake, I was about to throw out my keyboard and even pc right into the window! Now, when I have gone though the one whole game playthrough, looking at it with bleeding modder's eyes, I can't really comprehend where you and other modders are taking patience and strength for it!
Well, the result : I know that my gameplay changes are doable, albeit in a very crude and ugly way, now I need to cool down and take some rest and create a plan of my future course of actions.
There will be no way back, after I start making changes in meta data of bsp files, so I must now decide for myself, what i will take from 11.5 and what not.
