Will anything bad happen?

AS others have said: Do NOT do it. Cohabitating two snakes for ANY purpose other than breeding, is stressful to the snakes and potentially dangerous. There is absolutely no good reason for you to put them together when you have separate cages for them now. This is, to be perfectly blunt, an asinine thing to consider, and your comments and retorts to members here who are simply answering the question YOU asked indicates that you are immature and not as experienced in snake-keeping as you seem to think you are.

You didn't get the answer you wanted to get; boo-hoo. Either listen to good advice and put your snakes' health and well-being before your own curiosity and stubbornness, or stick them together and take a huge risk. You're going to do what you want anyway; why even ask a forum?
