Is there a way to connect a Thunderbolt 3 device (for instance a TB3 hub) to one of the Thunderbolt 2 ports of the MacPro end 2013? 
The Apple adapter from TB2 (female) to TB3 (male) mentions to be "reversible" AFAIK
Would it be possible to use the TB3 male side connected in a TB3 device and then use a male to male TB2 cable (if there is such a thing
which I don't know!!!) to connect it to one of the TB2 ports of the MP 6.1? 
Or exists an adapter which adapts TB3 to a TB2 port... instead of the other way around as all the adapters I have seen including the one from Apple?
I understand that any such connection would have just the speed of TB2...but I would like to find a way to phisically connect TB3 devices on one of the TB2 ports of the MacPro trashcan!
Thank you very much for any suggestion, solution or product!
