Does anyone have any suggestions for the best places to link up GR10 and GR11? That DOES sound like a fun idea. I would intend to camp so villages are not an issue.

When I did it I started on the GR10 crossed to the GR11 back to the GR10 , across to the GR11 again and finished on the GR10. Why? because there were areas I wanted to visit on both routes. Most of the time they are at most 2 days apart, often only 1 day. So rather than 'best' - which I can't answer - ask yourself 'why'.
