If you have a utility room withna floor drain, be sure to check for level, since the floor will most likely be slightly sloped.
For the rack itself, you mightnwant to check out tedsfishroom.com - he shows how to put together a very stable basic rack out of imple 2x4's that I'm sure you could trim out to your own taste when time and/or budget allow.
The utility doesn't have a drain unfortunately. The floor is also even, I checked for two reasons before. 1) to see if I could use self leveling concrete to resurface the floor and 2) to put our fish tanks in place! Most of them are all currently sitting where we want to build the stand. Thanks for the link!

2x4s are fairly inexpensive. Design it so that it will stand up by itself (without any hardware). Then when you put it together (with hardware of course) you will ensure the wood (not the hardware) is supporting the weight.
If you take a look at some of the larger tank stands available, you may be surprised at the small quantity of wood used. My 125 gallon stand (API stand) made me nervous about filling the tank but it is doing just fine.
I like your way of thinking about the support. I do design that way but did not think about it quite like that.
And you are right about how the stands are built. We have two custom stand and three store-bought stands and they certainly seem to be very lightly built but they hold a lot of weight.
I am now looking into doing aluminum extrusion but I'm waiting for some companies to call me back on prices and searching for used pieces in the mean-time. I found someone else's thread where a member mentioned finding used 80/20 extrusion pieces.
We changed our layout slightly. Here's a new very very basic pic.
I drew it as an idea of using the aluminum extrusions but I think it could work for 2x4s too. I'm unsure of the front to back span and the 4.5' span at the top and whether it will need more support. It's a 24" depth.
