Using C-beam for large OX

I’m building a 1000x1500 OX. I understand some of the tradeoffs (I know deflection increases as the cube of the arm) but my purpose for this is relatively large-scale wood projects, like chairs, so that I’m not expecting micron precision…

It looks to me like I could use 1500mm C-beam for the Y rails instead of 20x80 extrusion, at the expense of 40mm of X travel. It should be stiffer, and I can’t see anything in the design that it would interfere with. Anyone know that I’m missing something?
