Mounting Issue

Hey everyone, I hope everyone is well. So I have a problem, I would like some input on. I have a pole now, but I need to move it to a different space in my house in order to get practice in, as the old space was small, has no privacy, and others can just walk right into me during a move, or flow. The problem is, the new space has a vaulted ceiling with exposed rafters/beams, ( see the photo) and is over 11' in height. I want to get a permanent mount, because the dome won't work, but I am unsure how I would go about setting it up. The rafter/beam in the middle is almost ideal in terms of placement, but its more likely the pole will have to be a little to the right to be centered in the room, and to avoid hitting into anything when spinning, but then it won't be under a beam or stud as recommend. To add to that ,the dimensions of the mount means it won't fit on the rafter, so even if I didn't mind it off centered, there's still that tidbit to deal with. Has anyone dealt with a situation like this before, how did you work it out, does anyone have any suggestions on what I can do. All help is appreciated. Thank you.
