I did something similar about 40 years ago, bought a 20 ga field Lightweight and had a new stock semi inletted. I finished the stock work including checkering and had the barrels reblacked. I should have done the barrels first because they didn't come out very good. I could only do this because I bought it cheap, the semi inletted stock wasn't too expensive and I didn't have kids at the time. I also had young eyes. It was a learning experience and the gun came out fairly nice.

This ain't a dress rehearsal , Don't Let the Old Man IN
