Stand question for 45 gallon tank

[Beanz]

Hey all, so i have this stand that i built about a year back for my 45 gallon tank and i have to say that it is a crappy stand cause i can only fit a 10 gallon (very tight to fit it in) for a sump. I have emptied the 45 cause i'm not using it right now, so now would be the perfect time to make a change to the stand. What i am thinking of doing is taking the center pieces out or even just one center brace so i could fit a bigger sump, or fuge into the back of the stand. The "legs" if you will are two 2x4s screwed together to make a 4x4 would i be able to get away with just one leg on each corner?

Here is a pic of the stand to help you get an idea of what i have.
