How to remove this interlace/blending/chroma bleed?

[Maguku1738]

Hi, I have recently acquired an anime Blu-Ray which is interlaced. When using standard deinterlacing I get blended frames such as this.

Digging deeper and looking at the individual interlace fields I can see that the chroma bleed/ghosting is present in each field.

Is there a script/tool/plugin which can detect these "bad" frames and replace them with good ones?
I already tried multiple filters in Vapoursynth/Avisynth but didn't get any good results.
Thank you in advance for your help!

# average difference between compared frames
mp = mt_lutf(diffp,diffp,"avg",expr="x")
mc = mt_lutf(diffc,diffc,"avg",expr="x")

# build conditional masks based on the caculated comparisons
maskp = mt_lutxy(mp,mc,"x y < 255 0 ?")

# finally merge the luma of the tfm with the chroma of the srestore clip accordingly to the binary mask
MergeChroma(luma,chroma).mt_merge(chroma.selectevery(1,-1),maskp,luma=true,Y=2,U=3,V=3)

Thank you for sharing your code. The video you sent looks perfect!
I got hung up on Srestore error: "I don't know what AvsPlusVersionNumber means."
I downloaded this Universal Pack which thankfully worked flawlessly and fixed the issue!
Thank you once again!
