I think a 6.25" ride height (bottom of frame rail to the ground) is plenty of room. I set-up all our stuff to run a 5" ride height. I know you have been discussing the height the bag is designed to ride at, and this is critical to have it function properly. Set the bottom of the frame rail to your desired ride height off the ground and then figure your bag mounts out. I would recommend a tapered sleeve on an over the axle set-up... the ride quality will be much better than a convoluted bag. If you are planning on 'possibly changing over' to the tapered sleeve later and run the convoluted now, keep that in mind when building your mounts.
