This would not be good to do mainly for 2 reasons. First, fish need oxygen in the water to live and oxygen gets in the water (and CO2 gets out) at the surface. It's a false myth that an air pump will add much oxygen to a tank. Studies have shown that very little gas exchange occurs on the surface of bubbles as they rise through the tank. It does help in that it brings water from the bottom of the tank to the top and constantly moves the refreshed water into the tank.
Secondly, with a small mouthed bottle it would be very difficult to feed and otherwise care for the fish.

To change a fish tank water effectively and safely, follow these steps: Turn off all electrical equipment in the tank. Use a siphon or aquarium vacuum to remove about 25-50 of the water. Use a water conditioner to treat the new water before adding it to the tank. Gently pour the treated water back into the tank to avoid disturbing the fish or decorations. Turn the equipment back on after the water change is complete.
