The G16 has a fov 28-140mm f1.8-2.8, but the G17 could have a fov 28-140mm f1.5-2.4. I don't know if they could do that, but considering the rather surprising fov 24-100mm f1.8-2.8 for the 1" sensor in the G7X then it seems like it may be possible. The G7X uses a lot of software correction of the lens so that is another thing that the smaller 1/1.7" sensor might need less of.
The equivalent of the G7X lens on 1/1.7" sensor would be f/1.1-f/1.7, 5.2-22 mm (24-100mm equiv.). Should be possible if you accept the same strong software corrections that are used in G7X. The corrections would be a bit more visible with the smaller sensor though, because of sensor limitations like MP number and noise levels.
Actually, I like my more modest idea better. Keeping things more modest may mean less compromises in the lens design requiring so much software correction. That is why I suggested just a 1/2 stop improvement. Or maybe a 1/3 stop. The G16 body is bigger than the G7X and the sensor is smaller. That probably means fewer severe constraints on the lens designer.
Physically that extrapolated lens would be 1.7x smaller in every dimension than the G7X lens (maybe smaller than the current G16 lens?). On a 1/1.7" sensor camera there is less need to shrink the lens because it is already a bit smaller relative to the camera, so a slightly bigger lens than extrapolated should be no problem. In that case it could have less distortion (correction) and better image quality than the one of G7X, or have an even brighter aperture. But don't hold your breath for such a complete redesign of G-series lenses
