I actually floated the idea to a conductor that they should do occasional excursions with 1-2 coaches but apparently management cares more about getting the full revenue value of a 6-car train.
Pic from the 2018 Day Out with Thomas event. Pity too, they could definitely dress it up as a relatively convincing Percy.
