How? How do you get past the physics, Boris?
There are very good reasons why no one has created such a lens yet. Just because the GR is compact, that doesn't change the laws of lens design. The format of the camera makes no difference... The GR is just a mirrorless camera with a fixed lens. The size of the lens is - to a great extent - affected by the focal length range, aperture, image circle size and flange focal distance (plus, of course, the optical formula).
You can have (a) a small-ish, fast zoom lens for a small sensor, (b) a small, slow zoom lens for a large sensor, or (c) a larger, fast zoom lens for a large sensor. What you can't have is (d)... a small, fast zoom lens for a large sensor. If you really believe that's possible, you must know something that conventional lens and camera manufacturers don't.
