FWIW, I could try and see if it will be possible to use the assign lib to
write something like

assign::add_egde( v1, v2, g )(vertex_color,10)(vertex_name, "foo" );

or maybe

assign::inserter<X> edge_adder( g );
edge_adder( v1,v2 )(vertex_color,10)(vertex_name, "foo" );
edge_adder( v1,v3 )(vertex_color,10)(vertex_name, "bar" );

when I add the new functionality.
