My first inclination was "go away Mr. Morrison, you've gotten too weird and people have moved on from your self-absorbed storytelling." After further consideration though, I kind of agree with him and wish that Batman would remain solo for a while.
I don't think it can be done properly though without canceling out much of the greater bat family. Furthermore, Bats would need to cut down on all these social visits he makes in other books. Also, nix his JLA membership (it's not like Johns understands him anyway). If Batman is truly angry over Damian's fall and wants to do the solo thing, there should be no half-assing it.
Seeing as that won't happen (the other bat titles sell too well, and DC won't cut down on his appearances), you might as well give the Batman another Robin.
