Not sure it would make much difference in the grand scheme of things, y’know.
Sure, there’s be a rush at first, might even be noticable to the locals – but much less intrusive than the several cycle races held across the moor a year. Geocaching is still a very very niche hobby and these might get 2 or 3 visits a week after that first surge of interest – that’s how many the three “Knights View” roadside caches I adopted get.
Some people can’t reach the remote areas of the moor for various reasons. I don’t see why roadside and remote caches can’t co-exist quite happily.
