o5 Control Head- Bracket for inside corner mount?

[buckyswider]

Hi all, we have a need to mount an o5 control head at an angle on an inside corner. My first thought is to cut the install bracket in the center, and then bend each 90° bend another 45° and using that to mount the head, but wondering if anyone is aware of anyone who makes a bracket specifically in this configuration. Or if anyone has any better ideas. Thanks!
