You just stick the magnetic backing to the existing glass plate for flatness and rigidity. You might have to bump the heated temp 1 or 2 degrees to compensate for the additional thickness, and you may lose a couple of mm/s of print speed at the high end due to the additional weight. That said, it is a very cheap and easy to execute option.

I look for high endurance drives which are intended for use with pi’s, dash cams, etc. they tend to come in smaller sizes due to the endurance requirements.
