Since B will also be redoubling, it can be tightened further:
Match to 2^(n+1) points. A is winning 2^n to 0 and is holding a 2^n cube in a gin race.
Well, it still seems like cheating to be considering the possibility of someone taking in a gin race. But maybe it doesn't have to be gin. The scores described is as lopsided as it gets. By taking, B can reship to 2^(n+2) and play for the match. Meanwhile, B only stands to lose only 1 point more than if he passes. So the takepoint can get arbitrarily low and a near-gin position could probably still be taken.
Here is a position that satisfies all criteria imposed so far and hits the bulls eye. It is not gin, not a bear off as the player on roll may not be able to bear off a checker, and not an invalid cube (actually not a cube at all as XGR+ evaluates the position as ND/T). I didn't bother to roll it out, but regardless, I am sure the position could be played with to find something else extremely close based on rollouts.
