Rans S6
While not one of your vintage types, a Rans S6 would fulfil a lot of your other criteria. They are good load lifters and are happy (in fact prefer) to operate on MOGAS. They are good short field machines and you have a choice of flavours. You could go for an S6-ESD (microlight) with a Rotax 912 engine. This would do all you require, without the need to convert to NPPL (SSEA). There are nose and tail wheel versions. I gather that Randy Schlitter, the designer and manufacturer, is over 6’ 5” tall and designed the aircraft to fit his frame.
You might also like to look at Jodels, although they may be more limited on the height consideration. They are nice aircraft and a bit quicker than the Rans, they do prefer AVGAS. Like the Rans they will need hangerage being a wood / fabric airframe.
Happy hunting on AFORS etc.
