I personally would not house any 2 snakes together, even the same species.
I have no experience of the 2 species you are looking at but have heard of some surprising horror stories where cage mates have been injured, killed and even eaten.
Unless anyone has clear evidence that this is a great idea I would be steering clear of it.
(PS, You might like to give folks a chance to finish work, responses will come but can take some time. Not everyone is connected to APS 24/7)
