Yeah, I would say that there wouldn't be a problem with at least trying it out and see how it does imo. I would honestly probably give it 3 weeks though. The first week you don't want to do anything but leave it alone and give it a chance to settle in before trying to feed. Then if it won't eat for the next two weeks, I would try a smaller enclosure.

Just make sure that if it won't take F/T, try live or pre-killed before ruling it as stress related imo. My little one wouldn't take F/T but took live without issues after the first week in a large enclosure.

It will likely roam around a bit at all hours during the first week. If it settles in to roaming mostly just at night and hiding during the day, I would say your 'probably' ok.

I would say the extra hides are a good idea, just to give plenty of options. Enclosure looks great though ! =) Hopefully it all works out for you and your son.=P
