PS, You say "a larger sensor does allow you to use a lens with a larger entrance pupil and gather more light". From that I get a "foolish" thought. Might it (theoretically?) be possible to build a low light camera using big entrant lenses collecting much light and have all this light focused on a minimal 1/2.3 sensor?? In a way like an astronomical telescope.

You may be intuiting something like a focal reducer ("SpeedBooster")
This is rear converter optics that "concentrates" an image circle to a smaller image circle which reduces the focal length and the f-number of the resulting combination.
