I don’t know if you’ll find many that have done it. Good results or not, the fact that it will work is not really subject to too much concern. No reason it couldn’t.
But why are you worried about putting holes in the body? Were there holes there originally, or did it start off life as a half cab?
If you’re changing from a half cab to a full cab, you’re already making a big enough change that no one will care that there are holes put in where they are supposed to be. Ford put holes in them from the factory for the hard top, so why can’t you?
Unless you are concerned about putting it back to half cab, or maybe even roadster status?
Value? The buying public probably couldn’t care less.
Or are you just looking for a quicker and easier method of removal and installation?
Regarding the clamps, I would certainly try to find some that are very low profile. Most of the ones I’ve seen are fairly bulky and ugly, and would not look very clean to most people.
Also, the wrong clamps could be dangerous to arms and elbows and other appendages.
