I've seen some try it! Not sure how it turned out though.
Some people will keep a flock with just roosters, called a batchlor flock. What if instead of having pairs of 1 hen/1 roo you had the two roos together and the two hens together. If you are looking for fertilized eggs this won't work...
A few people have been able to have a 1/1 ratio but often times the hen with get over mated. You could potentially try it, but you will probably either need more hens, or get rid of one roo :(
