I've done it, but they were clutchmates (a bunch). And really, I see no point. I did it just to experiment. From a husbandry standpoint, it was not easier to house them together. The cage got dirty faster and I had to watch things at feeding time. I learned that it can be done (even with Cal kings) but there is no benefit to doing so for me or them.
I think communal housing requires some experience with keeping snakes, and it sounds like you do not have that experience yet.
My advice is to keep them separate. It is far easier to do so for some very good reasons.
