Store bought tank stands are so cheap and flimsy top begin with, I would never consider removing a structural element, even if I planned to replace it.
(You know you would have to replace it if you took it out, right? Then you would trap your sump in there with no way of removing it...unless you tried to make it removable, which is another headache, but even if it was removable, it couldn't be removed with the tank set up, so it wouldn't even help).
