BRB's housed together, good, bad, or terrible?

[MGJ]

I have two young Brazilian Rainbow Boas currently housed separately and would like to hear as many opinions as possible about housing them together. My male is a Hypo about 2 years old an the other (sex undetermined) is under 1 year old so the size difference is significant. I've read in my books that they can be kept together in a large enough enclosure year round with the only potential problem being males fighting during mating season. I had them together for 3 hours but I got nervous and separated them. The little one seemed startled twice by the big one when they met and he was very curious. He's such an aggressive feeder, ready to strike at any movement. The internet scared me as I even read about one bigger boa trying to eat and killing a smaller one. That wasn't about BRB's but still. In the 90's I worked in a pet store that housed many large red tails together. Things seem to be a bit different these days in many ways. Maybe I should wait till the little one has grown? I'm hoping it's a female by the way. My end goal was 2 to 3 cages, 2 males, and 2 to 3 females. Thank you for reading this and any advice. If people disagree, I'd like to hear it to get a broad view to narrow my final opinion from.
