Did you look into fitting it entirely on the longtail, that is, not towing it but mounting it to the outriggers or something?
Some inspiration from back when I lived in Calgary. Meat powered cargo bike. The only "e" was "me"!
The tray was not needed to carry a bike, but if you were going to haul a MTB to the trails it could be worth it for the stability/security.
