We found an excellent website, AllExperts, which had very good instructions for transplantig a bald cypress, including estimating how large a hole should be. We recommend that woody plants, trees and shrubs, be transplanted in the coldest part of the year, when they are dormant and less susceptible to damage. We believe your tree is young enough and small enough to be successfully transplanted. The main tip we would give you is not to take the tree out of its old hole until the new one is ready for it, with the resident soil mixed with a good compost to assist in access to nutrients in the soil. Second tip (free of charge): after planting, stick a hose down in the soil and let water dribble until it come to the top. Repeat this fairly frequently for several months. This tree is accustomed to growing in frequently-flooded areas and almost can't be overwatered.
