Here is a picture of my fake pinrails on the W32. This is a modern adaptation, the pins are fixed and the assembly fits onto tabs attached to the mast
pulpits. This type of setup is available and can be adapted to affix to shrouds with a little imagination. I also have schematics for traditional belaying pins if you wish to fab yourself and keep traditional. A nice touch would be to make some pocket boards that would mount traditional navigation
lamps and attached to the backside the pin rail with pins, all on the shrouds.
