How suitable are the Concorde noses for retrofitting the Quiet Spikes? And what about Tu-144s?

I read an article in an engineering publication (Aerospace America) about the testing of it.  NASA fitted it to an F-15 but it was only for structural tests.  The principle, however, seems viable for any sized aircraft, you just may need a more layered spike (and as a result a longer one).  All it does is breaks up the big boom into a series of little ones.
