Mathematically, it looks like you want two more inductors:
Added inductor 1: same inductance as yoke, wire in series with the yoke winding;
Added Inductor 2: twice inductance of yoke, wire in parallel with the yoke/inductor 1 combination.

The net inductance will be the same as the old yoke, but the current in the yoke will be 1/2 of the old value.
