In Weight Tools panel in the left, there's a option "Invert", it solves your problem?

Use a VertexWeightMix modifier to subtract your non-inverted (dynamic weight painted) vertex group from your base vertex group, effectively inverting the animated (weight painted) vertex group. Example: I have a "pinned group" that is all set to 1. I dynamic painted a "paint group" that paints 1's on a base model weight of 0 (red painting on blue). Then, I use VetrexWeightMix modifier and subtract B from A, and now I have the animation of blues being painted on red instead of the red painted on blue. I hope that was clear enough.
