reviving question : fastest connection between nMP and oMP

Hello

hi, just reviving my question on what's the fastest connection that I can create between the oMP and nMP ?

It is possible to have ethernet over USB3 between the 2?
or maybe with a USB3 -> thunderbolt adapter in between?

cheers TIA
like someone else pointed out I can fit the oMP with USB 3.1

then get a USB 3.1 to thunderbolt adapter
