Since the 20/20a and X35 just getting normal upgrades like the Loop Brand has, then if Double deckers get purchased for service 35 and 27, then the citarios from the 35/27 could be cascaded onto either Limes, Highwayman or Fab57.
Also since service 39 will not come under the simplicity brand then the versas could go to Washington for service W5/W6 etc... and those cadets could join other cadets at Deptford, so service 39 could become all cadets while service 29 will all be scanias.
