@ jagabo. thanks a lot for your mask but it seems that the bobed variant isn't the right solution for this case as you are left with basically all the crap frames doubled and they can't be fixed well. But for other cases which aren't a mix of 3 different formats I will give this another go.
@ hello_hello: that is some pretty impressive work you did there but working like this analytic section based "every section gets its own special treatment" kind of work would probably kill me in the long run/would take me forever to get that right for a whole movie like this so I would prefer it to be a bit more simple but never the less thanks for your hard work as it shows basically a lot of clever thinking how to deal with special cases like this in general.

that is pretty impressive I didn't notice any blending in the film sections so your dupe interpolation seems amazing.
Would you mind sharing the script you used for this conversion? So basically the 29,97 variant of your script in post #12
and no worries if its VapourSynth I can manage to re-write those to an AVS+ variant

thanks again for all the help everybody, you guys are out of this world impressive.
