Is it possible to swap the FSB on a Polish tantal out for a Bulgarian FSB? With out turning the barrel down?

The barrel journal where the FSB sits are both different diameters and lengths.  It would require a lathe.

The Tantal averages a diamter of .562" with a FSB length of .850"
The Bulgarian is .572x1.3"

Damn. Anyone know how much it would cost to shorten a AK barrel? Wouldn't mind mind bringing it down to 16.5" with a pinned on 4 slot FH.
