I would suspect that you are safe going with any of the rims made for the Civic EX. These should have the same diameter as the hybrid, and not effect the gauges. There will likely be a weight penalty though, as I haven't seen the weight of the stock EX rims listed. You may be better off getting some lightweight aftermarket rims. The weight of the stock Hybrid rims is well documented here, and Tire rack and other sites have many nice lightweight rims available.
