Building a stand that will fit a large sump underneath it?

[Quo Vadis]

I am going to be building a stand for my 155g tank (48"x24"x32") and I want to design it so that I can put a 75g tank (48"x18")underneath it to serve as a sump for that tank as well as the 90g tank next to it. But I am a little unsure how to design a stand that is strong enough to support the 155g, but still has the supports far enough apart to slide the 18" wide 75g underneath it. Any ideas? I suppose if I had to I could use my 45g tank as the sump instead, which would only by 12" wide. Would that be better?

There doesn't need to be any center supports under the tank. You can build the stand with an open floor giving you plenty room for both tanks. You can slide the sump tanks in from the side of the stand.

What i did was just to slide in my sump through the front of the stand. I did not have doors or anything to prevent me from just sliding in the sump though
