You should start a 4th class list. It'd obviously take a lot more work since there are a lot more routes but would be just as useful I think. You could make several interested people co-maintainers to help you out. That might be a fun lesson in how that system actually works in practice too.
You could add Blanca's Gash Ridge (5.0-5.2) and the Blanca/LB Traverse (http://www.summitpost.org/route/157610/blanca-little-bear-ridge.html.... Roach calls it 5.0-5.2, though that page's maintainer apparently disagrees) to the list
