Using ExBlend (https://forum.doom9.org/showthread.php?t=175948) works nice.
Sadly there are no plans to port it to Vapoursynth atm.
So to properly do it I would first use Avisynth with ExBlend and export it to a lossless format and then filter with DPIR or a similar strong area cleaner and through Vapoursynth. The attached sample was created with Avisynth ExBlend and mclean, just as a proof of concept.
For those interessted here's also the script i used:
