Although I like the idea, I think it would be more expensive than people would want to pay. While the SKS is a relatively simple semiauto rifle, it is a machining intensive rifle for what it is. Of course, the fire control set would need to be redesigned to provied a decent trigger pull, and the finish machining would need to be much better than the originals to interest American buyers.
If it were to be done, Fulton Armory would do a fantastic job of reworking the old rifles. The biggest problem in appealing to the American buyer would be the caliber itself. If it could handle something like 6.5 creedmoor, or one of the 270 variants you could get much better long range performance out of the SKS platform. Of course then you would have to deal with the sighting options in a way that overcomes the problems the shortcomings of most of the existing sight solutions out on the market. A cantilever mount for a long eye relief scope - like used on the scout rifle concept - would be the best for optical sighting to maximize accuracy at range. I almost forgot the stock - length of pull is too short for most average people.
Between the tigger group, the sighting problems and the limitations of the caliber, and that short length of pull, that would make the SKS a much better rifle. But then, in the end you would still have an SKS... just a better looking and better performing SKS and the question would then be; How much are you willing to pay for one?
