Speaking of single chuffs, my TMCC Ten Wheeler from 2003 only has 1/rec because it is actuated by a bar on just one of the cylinder rods. Sounds pretty terrible. This thread has given me some inspiration to see if I can kick it up to at least 2/rev.
My guess there is no place for a cam in the engine unless you mill one out. You could do what RonH has done with a two lobe cam on the tender axle, use magnets and reed switch on a tender axle, or John’s chuff generator on the motor.
You will still only get one puff out of the smoke unit unless you install a new fan smoke unit.
