Very bad idea. Very bad. First off, they have different husbandry requirements...corns like it a lot cooler than bp's do. Second off, mature bp's could possibly crush baby corns simply by laying on top of them. Third off, while unlikely, it is entirely possible that the bp's may make a snack out of the corns. Forth off, bp's are NOT social creatures and would be unduly stressed out by the addition of more animals into their enclosure.
It is not even ideal to have two bp's sharing an enclosure. What may look like "cuddling" and "loving" to you is actually two snakes competing for the favored spots in the tank, and possibly one trying to exert dominance over the other. It is unwise to apply typical mammal-pet feelings/needs to snakes because they are in no way the same. If your snakes are growing well...both eating regularly...and shedding properly...then "living together" may be working for you, but it is not the best thing possible for the snakes. In the wild, they live completely alone, except for a brief "togetherness" to mate...and that's it.
Also, with two snakes living together, if one gets sick, it is likely to pass it on to its cagemate. And if one has a sickly looking poop, you won't be able to tell which one it came from. And lastly...again, it is unlikely, but still within the realm of probability, that the larger snake may make a meal out of the smaller one.
The choice is obviously up to you, but if you truly want the very best for your snakes, you will get them each their own enclosures.
