As per above, you could modify it, take some material out of the stock, flute the bolt, the barrel, and drill the center of the bolt knob out or flute it, though I bet you would be into it for around 400-600+ and I think you would be better to buy another rifle to carry at your shoulder for hikings, and get something like a eberlestock pack for that rifle if you plan to go to a blind or wait along a field for first/last shooting light.
I did the same thing with a rifle, thinking I would have an uber cool hunting/target rifle, mine is more of an anchor then yours, and I was mistaken in thinking it would work for both applications, but I still had fun getting some custom work done and still really like the anchor, I mean rifle.
