Corner amount for G6 180?

Do these not exist? Seems it makes for a great mount to see down both sides of a 90 degree building corner.

I’ve looked around and can’t seem to find anything ready made. May have to model up something myself. Seems like a great use case unless there’s just something huge I’m missing. I know its vertical range isn’t the best but surely there’s a solution for this somewhere.

Anyone seen anything?

Thanks.
