In the case of a keep left/keep right sign, it must be possible to have
a swappable sign that's fitted in a 'window' at the top and secured in
place somehow, to prevent kids playing around with it.

Then you can have an arrow either way, plus other symbols can be placed
in this 'window' so you don't need to carry a whole bollard for each
sign. You can have 'pass both sides', 'no entry', 'cycles only/no
cycles' etc.

Good thinking.

However what I meant, and expressed poorly, was which way the *bollard*
should face.
