Isn't that what I'm already doing by passing the following two to the algorithm?:
 
property_map<UndirectedGraph, int VertexProperty::*>::type indexMap1 = get(&VertexProperty::index, uGraph);
property_map<UndirectedGraph, int VertexProperty::*>::type indexMap2 = get(&VertexProperty::index, comaparableGraph.GetGraph());
 
Or maybe I am misunderstanding what you are saying?
