400mm (640) on 80D VS. 600mm on 5DMKIV

I’m trying to figure out if I can get away with a lighter setup and get the same end result. 

My options:

Canon 5DMKIV + Tamron 150-600mm


Canon 80D + Canon 200mm f/2.8L + Canon 2X EXT III

I am traveling internationally and size/weight is a big factor in this decision. Also, I will be doing long exposures (around 6”) so wind is another factor. Super Telephoto lenses turn into sails and are very sensitive to vibrations. 

The most important thing is to get the sharpest, highest quality image possible. It’s a total solar eclipse so I don’t have another chance if I blow it. 

What is my best option? 

I am also considering renting a 5DS R if I go with the 150-600.
