You should never co-hab two snakes together, so no you should not. Reasons being,
1) Cannibalism
2) If there is a regurge, which one regurged?
3) Sicknesses/diseases spread rapidly
4) Both snakes will be stressed (may even go off food)
5) Neither snake is benefiting, in fact they would rather be alone
6) If poop is weird, who's poop is it?
I'm sure others will chime in as well. Best they have their own enclosure.
