Regarding rice, if you do attempt a recipe with it, you should get minute rice from the store. That rice is already gelatinized so it's ready for mashing.
Would you care to be specific about why you do not like rice?
Gelatinizing it is easy: just cook it with too much water before mashing.
Minute Rice has no appreciable flavor, but if you're willing to spend an hour - even a few days ahead - on the cereal mash, I've found that brown basmati can be pleasant.
fwiw i have never brewed co3c, or any brew with maize.
