If you put two in the same enclosure you are going to have a big issue come feeding time. Really big issues once they get big. Also, what if one happens to bite and latch onto you? You would not only have to worry about that one but the other one in the cage also with all the action going on at that time. Seems better to me make two 8 foot long enclosure's, put one in each and stack them if your looking to save space?
