Yes you could no problem but you'll get more support for gantry from that plate if it was on front has the rails will be fastened to it and can't flex in the middle. Has it is now the Box in the middle could flex has the only support is on the back side and the rails applying all the pressure are on the front side.!
You'd be better with it on front and either another thinner plate across back adding bit of support or 2-3 10mm plate braces across back.
