Skill Window Extension

I've assembled a crapton of mods in my game, and make a cheeky playthrough with a crapton of skills. At some point, I've found that I'm unable to add any more skills to my play (with augmentations, to be precise) because of the skill window being too small to add anything to it. Can I fix it myself? Can someone make an extension for the thing that doesn't ass up the mod assembly?
