I would love to see SP36 with following options...
4x SST20-DR deep red 660nm (will require a constant current driver with ideally 12A)
4x Osram "White Flat" 2mm² (KW CSLPM1.TG) or 4x Osram Boost HX 2mm² (KW CULPM1.TG)...will require a new reflector design, new gaskets, constant current driver etc. but hey, why not? :-D
