I too had an LX7 for quite awhile, John - and your take on it is spot on and closely parallels mine: a really nice small semi pocketable camera with a fast lens and not only a decent zoom range but also a zoom whose optical qualities really impressed. But the sad truth is: I don't think that camera exists, or has ever been built. The closest Panasonic came was with the LX100 - a camera which nearly has the same height & width dimensions as the LX7, but a much 'fatter' lens (which sticks out more). It also has a micro4/3 sensor which is roughly five times larger than the LX7's 1/1.7" sensor - but, honestly, I rather liked the LX7's smaller sensor which, among other things, gave its lens superb close-focusing macro capability. True, it added an EVF also, but not a great one. (The LX100 also weighs nearly a quarter more than the LX7 did.)
I actually spent quite a few years searching for a camera which would do everything that my old LX7 did and my solution was to buy not one but
two cameras, neither of which are quite as pocketable as the LX7 was. One was the Fujifilm X30. It's a tiny bit wider than the LX7, but has a fast (f/2) lens, a nice zoom range, and a brilliant small 2/3" sensor which is actually significantly better than (and a bit bigger than) that of the LX7 - but at the same time it's also a brilliant macro camera. Like the LX100, the X30 also sports an EVF - but though it's small, it's a very fine one. Problem is, you need a slightly bigger pocket.
The other camera - also a tad bigger and fatter and heavier than the LX7 - but one which nonetheless manages to be surprisingly pocketable - is Canon's G1x Mark III - which has an APS-C sensor and a fine zoom lens -
and is totally weather-sealed, a huge plus. Unlike the LX7, it has a tiny SLR-style hump with an EVF but it's a superb small EVF, further increasing the general take-everywhere-do-everything utility of the camera. Its only 'downside' is a slower f/2.8 zoom lens - but the quality of the sensor more than makes up for that. (It also doesn't have the macro capabilities of the smaller-sensored LX7, sigh.)
But...there is good news, or light at the end of the tunnel:
there is a superb and tiny smaller-sensored LX7 replacement - it look like a near-clone of the aforementioned G1kMkiii - Canon's G5X camera. It's smaller than its APS-C sibling - its dimensions are almost identical to those of the LX7, and it weighs just a tad more than the LX7 - best of all, it has a fast f/1.8 lens - and a larger and excellent 1" sensor. I think if I didn't already have (and love) the other two aforementioned cameras - and I wanted a pocketable LX7 replacement - this would be it
