Was inquiring on if someone has ever modified a Mosin Nagant magazine so it would be flush to the underside of the stock?

Over the years I have purchased bare receivers and stocks and would like to make a custom rifle out of the parts. Not a Bubba job but a tasteful example. I have several original examples and would not modify a piece of history, but in this case they are just parts. I have never been a fan of the “pot belly” magazine on these rifles and if I was going to do this I would like to keep the single stack mag ( due to the rimmed cartridge) thus reducing the round capacity from 5 to 3 with a flush mount design.

Anyone have any pointers or seen this done before? I have seen a few examples on the web but not really clear if they worked

Thanks
