can i see your current setup ? your idea seems very creative and has a good thought behind it but there are a few things i would like to point out :
you will most likely mount the heat internal so you will loose height if you keep the shelf in the middle the bulb will be way too close
you will also have to mount linear uvb internal which will also take you alot of space
your substrate will also take a bit of the height since you have to put at least 4 inches of substrate for digging and so on on
i personally would not rip out the glass from the current tank and would look forward for a bigger second hand tank
the space issue i totally understand i had the same issue but somehow i managed to fit the tank in my own room ofc
so you will basically have more disadvantage with that build i would look forward to upgrade
