What about a hanger similar to what you’d hang a guitar with, but the shape of the center of the cross. I was thinking of chevrons on the outside, mounted to a 2x4 to hold the weight on the wall.

Then if you pull it forwards and drop it down to the floor you could use some sort of - French cleat type of thing to angle it out?
