I moved my juvenile BP into a 48x24 enclosure with no problems. The key is to have cover and things to break their line of sight. As long as it is cluttered up really well, I think he would be fine. You can get a bunch of fake plants and vines at dollar store or crafting stores. From my research and limited experience with my guy big wide open spaces stress them out. So as long as you fill up the big space really well there shouldn't be any problems.
