Nice work!
One thing nice about a super light rifle is that you can afford a little extra weight on the glass if you like you have to be more careful about what you hang on it as you will be subjecting the scope to greater recoil forces as well as putting a larger burden on the rings to holder the scope, especially a heavier one, and the mounts and screws will have larger stresses to deal with as well.
I made a couple
minor changes to the otherwise great thought.
(Your idea would probably be applicable to an equivalent rifle in a lighter caliber however.)
