The only thing I can raise is that I think Jazz commented that attaching supported rail to alu profile can be tricky depending on the spacing of the holes and the internal shape and thickness of the extrusion.... maybe you've already checked.... otherwise might be worthwhile checking with somebody who has seen both of these in the flesh so to speak.

From what I can see from drawings of the profile and measuring the sbr20 I've got it should work... Would appreciate it though if someone could tell me for sure otherwise with this combo..

Yep it will be fine.(Just for you joe.)

It's certainly strong enough, but the 50mm thick aluminium seems a bit over the top. It's a mildly interesting part to machine though so I'd do it cheaply as I tend to charge less if the part is interesting! You could replace it with 2 pieces.
