Not all Lyco and Conti engines can be upgraded to take mogas, as of now. Some may never be able to, either because of technical issues or because of the limited number still in service. I still see replacing those engines with equivalent engines that can operate on mogas as the easiest option, certainly much less painful than replacing them with a completely different technology (be it turboprop or turbine hybrid or whatever).
