Stacking doesn't increase the light pollution.  It does increase the signal to noise by average out the random noise created by your camera.

To see more stars you need to subtract the light pollution from your image and then stretch the signals from those stars to make them brighter.

Having less noise allows you to stretch further.

Never tried it from such light polluted skies but other forum members have previously got some stunning results from city areas.

Stacking from RAW rather than jpg will be important

Hope that's somewhat helpful
