Get rid of...
EF 10-22 and get 16-35F 4.0 IS - Yes, I think that makes sense. The L-lens will give you a similar angle of view with the 6D as the EF-S lens on a crop sensor body, but image quality will be better and you'll get the benefits of IS.
EF 70-200 F2.8 IS II and EF 400 F5.6 and get new EF 100-400 II - Actually, I wouldn't advise getting rid of your most-used and favorite lens. Instead, you might try selling the EF 400mm f/5.6L USM and purchasing the 2x Extender III to tide you over until you can save up enough money for the EF 100-400mm L IS II. :-)
