If you check out the following address, you will find that what you are talking about has been flying around for quite some time: http://www.experimental.ch/SwissMade/Gion_Bezzola/gb-3.htm
Sport Aviation had an article on the GB-2 Retro in February 1982. Gion Bezzola has gone on to design and build one more single place canard called the GB-3 Vetro. He does not sell plans. It appears that he has used the VariEze building methods and powers the pusher with a VW engine.
