Can be done, though some stuff (most) needs you to chop the old coupling off
completely. I'd use the "boxed" types which screw/glue under stock for
this. Coaches might need some inventiveness if fixed to bogies; if running
gentle curves, fix the couplings to the bodies like the prototypes ;-).
Some of the newest N items in the UK come with standard coupling pockets,
which can take Microtrain couplers as slot-in replacements (and thus
reversable without damage).
