you have the same problem, many of us have. what how to efficently store attachments when we are not using them, but be able acess them easily and attach them . My solution has been dollies. Harbor freight, etc. inexpensive. you can roll them in and out of their storage places.
As far as attaching the Quick hitch plow with the loader in place. I am not sure how that will work out.
I have a BX 2360, I have set up my tractor up with a versa-daptor from Jari. I can drop my bucket on to a dolly and roll it out of the way and attached the plow blade to the fel. arms.
I also have a set of forks from Jari.
A few pictures is worth a thousand word,
I hope this helps, and you and come up with a creative away to up a to be able to roll your attachments around.
