Yes and no.!!
Yes, the profile layout is correct but my design doesn't use the plate on the front. The rails sit top and bottom of the profile and the ball screw goes at the rear out of the firing line of chips.
However, I don't use round type rails so it's a little more difficult for you to mount the rails. If I was using those rails I'd bolt 10mm flat plate to the top n bottom of the profile and then fasten the rails to that. The plate on the front doesn't add much more strength than the profile does but does add weight and expense so I'd get rid of that if using my design.!
Another advantage of the rails being top n bottom other than saving cutting area is they support the Z-axis rear plate better because of the wider separation.

But your design with a slight tweak would work ok, but with the rails on the front your wasting cutting area, plus the ball screw is exposed on the front.
The tweak would be centralizing the plate or even lifting up so the bottom is flush with the lower profile. As you have it now hanging down it could vibrate because most of the cutting forces will be at the bottom rather than at the top.

This is a cut away of my design if it helps.
