Thanks for your post and apologies for the late response, I seem to have missed the post.
I have a pair of metal mule panniers which I kept from my Tiger 955i, but Metal Mule do not make a bracket for a Crosstourer. They require 20mm width brackets.
I also have the full set of Honda panniers, which I don't like.
I am at this point in time on the brink of getting a pair of the GIVI Outback (48L). I've fitted a luggage plate to the rear top on which I will use soft luggage (water proof roll bags). If I go down this path I will sell the honda panniers and also the metal mules. Will be sad to see the metal mules go, they good panniers. Thinking I will get these...
