For this purpose I want VFR so makemkv is doing what I want.
If you want to do postprocessing with vapoursynth you'd need to encode to ffv1 (or pipe) then extract the timecodes from the source, create a new file with your filters applied (it will play back at the wrong speed), then mux together the audio and timecodes from the source with the filtered (wrong speed) video. You won't be able to apply any filters that add or remove frames but colour correction and single frame image processing will be fine.
I don't actually know exactly how to do this but it is possible.
