Definitely a bad idea.
Post 320 Airbus moved the most circuit breakers to the avionics compartment. The ones left in the cockpit are resets, not power trip cb’s. Except some for window heat and whatnot. 350 went one step further and split the critical systems channel A/B between electronic circuit breakers and physical circuit breakers. Either way you can’t get to them in flight.
cabin cb are not much of a drama to reset in an attempt to recover some lost convenience items unless they were found tripped. Then they are to be left alone.
