Could you not leave the arm attached and use that? Burley have a nice a nd simple pin connection if I remember coreectly, so you should be able to hook it?
That’s what I did with my old fake one. Got a £5 hitch from eBay and bolted it to the wall. I also stuck a bit of yoga mat to the wall behind the trailer to stop the qr wheel stubs getting scratched/ground down. Btbh I left the wheels on most of the time.
