Sorry, I can't think of an easy way to do this. It is possible for two adjacent vertices to be in two voxels that only share an edge or a corner and not necessarily a face. Maybe if you increase the size of the mesh (and so reduce the distance between vertices) you will not run into this problem. I don't know of a command off hand that will do this, but I think Bruce may have something.
