This might sound dumb, but I'm not an engineer, I just play one at home.
My plate is 4'x6'x1" thick and has 1/2" holes already drilled so I was thinking of caping the legs with a plate and then bolting it to the underside of the top. I like the idea that I can disassemble it and move it if needed. I'll tie the legs toghether too, but my question is is there a need for a base around the perimeter? Any chance this could sag over time given a 5' span between legs?
