Does it still do well on your 7D with the smaller image circle? If so you should sell the 100-300/4. Be up front about it not doing as well on FF and I'll bet you'll still get a few hundred for it.

Yes it is more consistent on the 7D but 1:1 center crops show up much sharper on the 6D. I wonder if I'm going to notice less difference with the Canon 100-400 II as the dense sensor of the 7D probably benefits from sharper optics? Anyhow, 400mm on crop is going to awesome 

I might as well sell the Sigma and be honest about it as you say.
