The Evil Spanish Teacher

Hi, I’ve been using Blender for a little over a year, and this is my first project. It’s an animation about a high school. This particular scene is set in a Spanish class where the teacher is basically a female version of Tony Montana. Anyway, I’m having issues with weight maps and shape keys, hence the pulsating right hand. I know what’s causing it, I changed the basis shape after the shape keys were established, and I was wondering if there’s a way to fix it without having to go back and redo all of the shape keys.
