OP, those Weaver side mounts and the G4 scope left a lot to be desired and the receiver still needed to be drilled and tapped to fit them.
I will agree with guntech that the rifle is best used as designed buttttttttt not all eyes are created equal and I can tell you from experience, as eyes get older, they don't get better, which makes using iron sights next to impossible for many.
One thing to consider, that rifle may have some collector appeal. There seems to be a growing interest in period rimfire 22 rifles. Drilling and tapping would lower its appeal
That being said, I have seen the receivers on these drilled and tapped to take 3/8 dovetail mounts (10mm) and I have seen these receivers with two dovetail slots cut down their length, to accept the modern clamp on mounts. IS THE RIFLE WORTH THE PRICE OF HAVING THIS WORK DONE?? You just may be further ahead to purchase a modern used 22rf bolt action rifle that is already set up to be scoped.
As for the bolt clearing the scope??? There is actually a fair bit of room for that, depending on base height. The bolt is easily bent to clear as well.
Again, IMHO it would be cost prohibitive if you can't do the work yourself.
