So I was trying to work this out myself, googling around and found this page as the most helpful one. The basic idea came out right, but just a bit to much hassle to achieve the goal. What I ended up doing was that I created a new mod in MO that contained all the vanila tintmaps and just had that one overwrite everything else while in creation kit. Seems to have solved most of the issues. Ps. Sorry about necroing this topic, it's just that there wasn't really many ansvers to the issue out there so thought I'd share it. Ds.
