I find your project to be one of the most beautiful Mosin-Nagants I've ever seen on the web.
Can I buy it?

All joking aside… There might be a market for your Sako-Mosin-Nagant scope mount.
Atleast I would like to buy one.

My everyday moose hunting Mosin is the .45x54R I made a few yars ago.
The seccond most common rifle of mine is the 8,2x53R made by a gunsmith at Sako.

Only if the weather gets really bad, will I grab my composite stainless "something else than a Mosin-Nagant, thus not worth to be mentioned" rifle when I go hunting.

The most interesting Mosin-Nagant I ever saw is one chambered in .45 ACP.
It loads from a 1911 pistol magazine...
Just to remind you guys that there is no limit to what you can make out of a Mosin-Nagant.
