I think I found the perfect set up for folks that were discussing this last week. Us e your Genos, Pa4x , G70, EA7, SD7 etc on top and this keyboard controller with weighted keys set up beneath.. It would allow less than 4 inches surface to surface of the keys. (Compared to 2 and 9/16 on a Hammond).
