You just moved the target, didn't prevent dust

If you put a clear lens farther away from the lens, all you did was alter the part of the camera that you need to clean.   Dust will just collect on your little protection lens instead of back on the sensor.  Nothing has changed in terms of dust prevention, but you've significantly altered the design of the lens mount.

And FWIW, the top layer of the sensor is protection glass already.  The actual sensor is not exposed.
