Swapping in parts from some later forks would be a new experiment I think. I've never heard about anyone trying it but hey, that's how we learn new things about this bike.
The Minton Mods were originally for the later 35mm forks but I don't see why they couldn't be applied to the earlier ones as long as the number and size of the oil holes in the damper rods are similar. When I first did the Minton Mods to my '78 forks, I waited until I acquired some spare damper rods. I didn't want to mod the only ones I had just in case the experiment didn't work out. You might consider doing the same.
