It seemed to work okay for me. I've attached an example file.
Please note that the values used in the example file are likely not
optimal and that I've probably missed a slew of required modifications
(I just copied over the settings from size12.clo). For instance, the
size of the text on the title page hasn't been modified.
Please let me know if this file doesn't compile for you or if you
encounter other problems.
