That should be enough to keep you busy ;)
I think Brad and I did about 7 hours to Champagne Castle and back last year (but I don't have an official time for that, so might have to try it again).
The Sterkhorn time is pretty crazy! I'll definitely have a go though!
Also keen to go up to Mafadi, but not sure if I'll have time now, but will be back in Jan, so will have a go at that then otherwise :)
Oh wait, nevermind- brad and I didn't quite make it to Champagne, only got to the closest peak from Grays.
