No, never, no bueno. Snakes are solitary animals keep to them selves. If you keep 2+ in the same enclosure one will become dominant and maybe cause others not to eat. "cuddling" is not cute it's a dominance action. If money is an issue tubs are a GREAT alternative and actually are all around better to keep a BP in. Not as pretty but it's w/e.
A quick easy way to help you out is get a shelve of melamine wood. Buy like 3-4 feet of flexwatt and tape it to the shelve. Now attach the flexwatt to the thermostat your already using and adjust accordingly. Tubs can be place next to each other on the shelve (it can be on the floor or on the wall it's w/e just make sure ambient temps are above 75F). That will take you like 10 min to put together and about 30 bucks
