Ordinarily, my thinking would be to try replacing the rear wheel, cassette, chain, and rear brifter, and see how everything plays together, but I'm not even sure that would do it.
I think brake cable pull ratio is still pretty much the same.
As far as shift though, definitely different. And I think even if he wanted to change the rear the 11, and leave the front as is, it wouldn't work out so well because of the narrower 11s chain and the wider 9s FD cage. You could probably get it to shift, but it would likely be at the extremes of what the FD could do. Not to mention 11s FD's have that stupid plastic bumper on them now too (thanks a lot Shimano).
