Hello,
FYI, I am building 3 tanks (2 of 14"Hx42"Wx21"D of 53 gallons and 1 of 20"Hx25"Wx21"D of 45 gallons) of roughly the same size of various dimensions. I use 3/8" material throughout. The top for all 3 have eurobrace and the 42" wide ones have 2 front to back catwalks. Anything less than this I won't be comfortable to be with as this is the minimum requirement.
I will not even consider eliminating the catwalks. However, if it is the overflow side you may get away with a small cutout on the border brace. It really depends on the way it is done (ie where and how it is attached and stuff). You also have to watch for the cutting of the radius.
