Might get away with 16mm, but I'd say minimum 20mm rails.
As it is the design will be much better than what you have made from plywood, but it has the potential to be significantly better with the changes already mentioned. Though it would be nice to use profile rails I don't think it's worth the money for this size machine as you will still be able to cut aluminium perfectly well with SBR20 rails on Z (as I do), just not quite as fast as with profile rails.
