Yes crazy idea, you don't run back to a vehicle that is on fire.

The hand held is just to put out the field you just lit up.

It is OK to pull the plate and put it back on while the car is elevated.

As long as you don't drop the car onto the suspension with the plate off you should be fine alignment wise.
