I know it'd be a stretch considering the limited number of real world examples, but I'd love to see a well modeled "pregnant" Cub (thats a 3 seat conversion via a widened midsection) like ZK-BKJ, and a long-range/STOL conversion like ZK-SHG had (greatly increased span, down-turned wingtips, larger square-cut tail surfaces and about 3 times the fuel capacity of a normal Cub) both were 180hp conversions.... *sigh*
