Grand Canyon - routes on the Coconino sandstone walls?

Was at the canyon yesterday doing the basic touristy stuff with family and had the same thought I do every time I go: are there any (decent) established multipitch routes on the miles of Coconino Sandstone walls accessible from the rims? Something like Screaming Sky Crack but with 1 mile of hiking instead of 32? Anyone tried and failed?

I'm sure there's no shortage of choss but in the miles and miles of walls surely there is some good stuff worth doing.
