You have the experience, the know how, and the space? Then do it! I'd go with the baby too. I don't like to taking others problems off their hands, but I do do it...just only one or two at a time. Rescues are a lot of work and I give props to anyone who does it, but it's really not my bag of chips. I would think (I don't have a whole lot of experience with burms, but my friend has two of them) that you can take the size, temperment, feeding response, and any and all else of a large Boa and double it. Strike range on those guys is remarkable too! Wowza! Heck of a reach they have. Good luck!
