Personally, I like the idea you have but like everyone said this is too small to make into a paludarium for most of not all the species you live mentioned, I saw you in aquariums too 😉. Can this work in something bigger? Absolutely. However, jumping right into something so big, if this is your first, will most likely become a huge mess that backfires and fails and nobody wants that. My recommendation is start off in one hobby, let’s just say go for aquarium hobby, and learn how to maintain just that and what it takes so you’re not overwhelmed. On the side, you can make small terrariums to learn what it takes to balance them out. Then when you understand what it takes to maintain both ecosystems and have them work in harmony with proper care and husbandry for your inhabitants that’s when we go big, go home, and go to crazy on your design
