how can i use multiple tech tree extensions in career mode??

[claclawolverine]

hi everybody, i've recently discovered some interesting mods that i would like to use simultaneously in career mode, and they are impossible innovations, interstellar and the various near future technologies. all of them have got a tree.cfg file and the last two have got a folder called treeloader with a treeloader.dll file in it. now if i overwrite this file i suppose that one of these mods won't work properly, while if i don't overwrite them one of them surely won't work. so, my question is: how can i use multiple mods with treeloader.dll and tree.cfg files toghether?? and when i've done how can i control that everything is ok? because i can't see if the treeloader will load correctly the last parts of the tree before unlocking them, and to unlock some of these features i could have to play for days. in sandbox mode it's everything ok but i suppose that it's ok just because it loads every part without looking at the tree tech(s).

yesterday i saw that the tree.cfg files are pretty easy structured so i was wondering if i can modify a tree teck just by writing in the correct part of the tree.cfg the names of the new parts. for example can i copy and paste the names of the new tree nodes of, let's say, interstellar, in the tree.cfg file of near future tech? will it work? do i need also to move the parts in interstellar mod in the same folder of near future, or is it not necessary, or is it necessary to change the treeloader.dll file?

for now i have tried to keep all the treeloaders in different folders (one with the original name, the other with a similar one), and i added just the tree.cfg file of near future, but the game sometimes crashes without a reason and without releasing a crash report (just stops working).

do you have any idea on how can i solve this problem?
