I think you answered your own question Zeitfest, just not cost effective.
Having a motor generator pair you've increased the amount of copper in the system compared to a single inductor in a buck converter. You'll introduce a lot of weight from the shaft and motors that would be expensive to ship as well.
It still needs electronic control of the field coils for MPPT so still requires a software solution. Downside now you've got bearings that would wear out as well.
A modern high quality electronic solution is going to be cheaper to implement and lower maintenace due to lack of wear parts.
