Just picked up on these. There's no way The Avenue or Orchard Street could be used by a full length single decker.
The idea about heading along The Bronx could work, but turning right onto Durham Road could be iffy with a canny wait.
The only other suggestion (apart from it using an MPD and Harris Bank) would be a loop of Fell Bank and Mt Pleasant Road that runs parallel to Fell Bank, with a short run along Portmeads Road, before heading back down.
