Thank you!
I have thought of a few options yes! I'll either upgrade them (or just one as the new 'spare' hide) by making a wider taller base to attach to (one of the reasons I made the "mouth" as wide as I did so it can fit a larger ball python) or just replace them with larger matching hides and save them for my hopefully-one-day-second snake. Currently they are stuffed with a fair bit of substrate to make him feel all nice and snug, so I'm hoping they will last for a bit lol.
I do have plans on making another Zelda themed hide, a BOTW shrine as a spare or humid hide when it's time to use his full cage
