How do you plant to heat and light the tanks? Your heat light will be the biggest limit since you are planing to stack the bulbs will be inside the tanks, So take into consideration the socket, the bulbs and 6" min distance to the heat source for safety from the ceiling to your dragons back. If you plan to use T8 lighting it is difficult to keep 6-8" from the UVB and keep far enough from the basking bulb if both are overhead as recomended. T5 lights are a better option and will help brighten the cage more too but the fixtures are expensive. You will not be able to use MVB lights in either size tank. If you want to use climbable furniture, like a branch or anything plan for that too, I found it's pretty easy to use up 24" of height especially with a grown dragon who needs bigger furniture.
I wouldn't go smaller than a 4x2 foot print personally, and the 4x2x2 is pretty easy to make with a little more than one 8x4 sheet of plywood. Lots of people stack them too.
Just my thoughts, there are plenty of ways to do it.
Not correct : an 80W MVB ( such as an Arcadia D3 MVB ) will work a treat in an enclosure that's 18" tall. See

That's what I did until I decided to go to Phillps P38 spot lamps to provide heat and sunlike lighting.
My beardie and bluetongue skink enclosures are stacked (double deckers). My Water Skink enclosure sits on an old coffee table.
I'll give a tip, put casters on the bottom of the enclosure bank with a kick rail with about 1/4" clearance from the floor - will make things SO MUCH EASIER when you moving the enclosures to clean under and behind them and recapture rogue insects. An enclosure bank is pretty big heavy awkward to move about once fitted out and furnished and occupied unless you put casters on the bottom of the bank.
