How to temporarily change player camera to "external BP" camera?

Post a screen of your Blueprint and I’ll take a look.

Alternatively, you could try something like the BP below:

This simulates a Security Camera and tracks the player’s movement.

You’ll need something to trigger the camera though, I setup a triggervolume inside the Level Blueprint to switch to this camera. Let me know if this works for you or if you have additional questions.
