I reckon if you oval up the securing holes on the bass side of the bridge about an eighth of an inch (towards the tail, of course), and pull the bridge assembly firmly towards the tail of the guitar while tightening the securing nuts screws VERY TIGHT INDEED you may get it about right. Mark the front, even if only with removable tape, before you start, so you can see how much change you have made when it all goes back together.

I think one reason these are pretty stable tuning is the multilaminar neck, which I am sure must be very rigid. But do NOT apply shock to the neck or it becomes, I am told, multidelaminar.

Mooh is right about checking the nut too, but if it was the nut that was the problem you'd hear all the fretted chords in the root position that involve open strings being absolute wolves.
