Well, any combination of summer and winter grains that will grow in your area
should work fine. For the summer, you might try buckwheat and/or corn, and for the winter wheat, rye, oats or whatever should work fine in your area. I haven't had the chance and don't have the space atm to try a similar rotation, so I can't really speak from
experience. I would definitely use a deeper rooted legume than clover, though, or preferably a mix of things (ie residual cover crops).
As for no-dig, generally you have to use deep/thick rooted crops
first to break up the soil, add biomass and pull up minerals. A good mix of cover crops can do this in 1-2 years.
