I think the LX100 is worth a look if you are looking to do street photography.
It has a standard 24-70 FOV zoom range lens that is f1.7 at the wide end and f2.8 at the long end and, as has been discussed on here multiple times, its a great lens that happens to have a free body attached.
Control wise it has dedicated aperture ring, shutter speed and exposure compensation dials so its really quick to use and, as they are more substantial than those of the GR, I prefer it operationally over the GR.
You'll lose the thinner form factor of the GR by virtue of the size of the lens but the actual camera body is more or less the same and the LX100 is still on the plausible side of pocketable. It is certainly far more compact than even a small MFT body like the GX85 with an equivalent 12-35mm f2.8 lens on it.
What you will gain over the GR is a serviceable EVF and 4K 24p video recording when you feel the need.
The clincher really is the price in that, although they've gone up in price like most used products in the past year, you can still pick up a good condition LX100 mark 1 for about £250 or less. For context, that is way less than half the price of a used version of the 12-35mm f2.8 lens let alone the cost of an MFT body to mount it on.
A word of caution regarding using the P4K with native MFT electronic lenses such as the Panasonic and Olympus etc is the amount of lens corrections that those MFT cameras do, particularly on wide angles.
The P4K does not have any of those corrections so if you do go for a P4K check any prospective lens on the camera to make sure you are comfortable with the uncorrected performance of it.
