The evil that is Coily will not die easily. ;)
Is the conversion from PAL to NTSC a long and laborious process?
At least the evil is reduced by half now.
No, it is a quite fast process, thankfully.

Came across a THX still on Ebay with an interesting little detail in it.

Nice still. Yeah, another car in the upper corner. Don't think I've seen that one before.

With the source already this badly halo'ed, you must de-halo, especially before applying any sharpening, to get decent results. To demonstrate:
I max'ed the settings on "DeHalo_alpha" (rx=3.0, ry=3.0, lowsens=0, highsens=0), a script I copied somewhere -- DeHalo_alpha(clip clp, float "rx", float "ry", float "darkstr", float "brightstr", float "lowsens", float "highsens", float "ss") -- but couldn't make all the halo-ing all disappear. Maybe there's a better version? It softens the picture a little but following up with "LimitedSharpen" (made it pretty strong here, too -- strength=600, soft=true, overshoot=0, exborder=4) nicely brings the crispness back ... for a better overall result. (Of course, you would tweak the settings for better balance than I did for this proof-of-concept.)
The thing is, no sharpening was applied, that is how badly oversharpened this LD is in many scenes, the PAL transfer don't suffer it for the most part but the NTSC is so much better in terms of detail, colors, cropping and in how clean the capture is, so using the PAL is not an option despite the severe haloing in the NTSC transfers.
I was actually about to try out some de-haloing just as my PC crashed all the time so I was never able to see the results. Thanks for posting those examples, much appreciated. :) The result of de-halo is what scares me, the halos are reduced, not gone but you end up with side-effects that is worse than the original problem, but I'll see what I can do. I can clearly see some "water-color painting effect" in your LimitedSharpen example.
