I've been doing this (pic) for mounting commercial braces. The effect is similar to Noel's. But, your aluminum brackets allow the braces to be mounted nearly a half inch further outboard -- a good thing when foot room is typically limited.

: That is one of those, "Why didn't I think of that" ideas.
: I am going to have to try that!
: I don't really like making those brackets. Hate flying aluminum
: chips.
