Sculpt like behaviour

We have a mesh that wears clothing. But we have clipping with some combinations of clothing. We would like to know if it is possible to offset vertices so that it solves the clipping? We have a weight painted FBX mesh. We want to make an option where we can take a troublesome combination of clothing and generate a special map that offsets specific vertices so that they are not clipping anymore. We would like to know if this is possible or if someone has done this before.
