A lot of people house their bp's together but this is generally not a good idea. It is stressful for a non-social animal to have to live in a limited enclosure with another one. There can be competition for good thermoregulation spots, etc. that can cause one snake to dominate over the other causing poor health on the other snake.
Another problem with this is when one gets sick the other is exposed. Also, it would be difficult to tell who poop'd, who shed, etc., so that problems cannot be identified quicker.
Even breeders do not house their males and females together at all times during breeding season. They usually only put the male in the female's enclosure 2-3 days out of a week to give them a rest period.
Just some thoughts.
