That would be my suggestion as well.... I don't think you can make topological 
changes to the mesh like that and have libmesh continue working... it kind of 
assumes a hierarchy of refined / coarsened elements as the only modifications.

Maybe Ben will have a better idea... but I think a new ES and MeshFunction are 
probably the way forward here.
