A very interesting question but I don't think it would fit the cultivar definition of the International Code of Nomenclature for Cultivated Plants (ICNCP) under which the AHS has to operate. It also wouldn't conform to the AHS's definition of the originator of a cultivar, which is " The originator has been determined by the Board of Directors to be the person who has ownership of the entire cultivar when it blooms for the first time".
