Over the years I've seen more than one attempt to take rifles not generally known for their accuracy and build them into accurate guns.
One of those was an attempt to turn an FAL into a rifle that would be competitive in High Power matches. The result was a rifle that was indeed quite accurate, but not quite as accurate as the AR15s and M1As being built and used for the same purpose, and at a significantly higher cost.
The other was a user here who set out to build a 1 MOA SKS. His posts should still be archived, and they make for interesting reading, though, as I recall, the project was quite expensive and involved a fair bit of gun smithing, as well as shooting Lapua ammunition.
There have been other attempts to do similar things as well.
In all cases, the results were guns that, while more accurate than their off-the-shelf brethren, were still extremely costly and still not as good as the "standard" rifle and caliber choices for the guys who were actually interested in shooting competitively.
If all you want is an AK that you can use to troll inexperienced AR owners shooting from the bench at the local range, I'm sure such a project could be built, but it strikes me as a fairly expensive undertaking just for the sake of trolling, and not something that's going to actually be capable of the sort of accuracy you'd see from, say, the guys competing in Service Rifle matches.
