Modifying the damage is handled by the Improved Critical extension.
Adding this to the Improved Critical extension shouldn't be hard...I can take a look and see if you want. This would be similar to how 2e handled critical rolls (depending on how the the wording of the DMG was interpreted), right ? We always doubled damage on a critical hit like you are talking about.
