Eurobracing

My tank is similar in size (70x20x24) and has no center cross brace. Euro bracing is ~2.5" wide using 1/2" glass.

Your flow will probably be under 1000gph so really don't need a drain bigger than 1.5", also could consider 2x1" bulkheads for return and Herbie backup. This would allow you to keep your Overflow chamber fairly small.

Check RC Headloss and Drain calculators, they will give you a recommended linear weir length to use for planning the chambers dimensions.

Why not just use a bulkhead and plumb with pipe to a different location.
Your over flow does not need to go in the center.

Doug:
Why do you need to remove the center brace? You can still have a middle overflow with that brace in place. Worst case you can drill a hole in the brace if you need something through it.

Was just thinking if a fish or something were ever to get stuck in it I would never be able to get it out. And I do need get some silcone on the inside edge of the overfow box ...dont I?
