How crazy is this idea?

As mentioned, no need to drill a hole as it already exists in those pieces. I did think about needing to make room for the binding bolt, but as long as it holds the pieces and lets them pivot, they don't have to look neat. If necessary, I just won't push the pieces flush against the bottom/top of the bracket, but instead leave a little room for a bolt head or whatever.

Ombligo, those pivot hinges look nice, but the ones I saw in a quick search were a lot more than the .68 ea. for those U ties I'm considering.
