on the other hand, more different PAL edition could be used to average/median the captures, removing a lot of analog noise inherent of the laserdisc format itself.

This could make your version stand out, as you do seem to have many PAL LD sources on which to draw. If you use NTSC, I don't see that your version would differ greatly from the captures that althor has already uploaded. And you'd probably have more fun trying to average out all the PAL versions, so I vote for PAL.
