Scaling bones in edit mode does not auto scale translation in pose library

At some point I decided to change origin and scale of a model and its armature, the armature already had some poses saved in pose library. Latter I discover that scale bones in edit mode does not auto scale translation saved in pose library for bones that not only rotate but also move.

Is there a way to avoid have to redo all poses? How can I scale the translation of bones in pose library by the same factor I down scaled the bones in edit mode?

Update:

What is happening to me is similar (or the same thing) to this: http://blenderartists.org/forum/archive/index.php/t-195566.html

I took note of the value used to downscale the model, so if I visit each pose, multiply location by that value, and save, it may have the effect I’m looking for. And I prefer that to re do each pose.
