I've recently bought a Leica D-Lux 5 for this and other similar uses, and I have to say I am very impressed. It is quite well thought-out, reasonably practical to use, and feels pretty well built, too. It prints up to A3 size very well indeed. I recently had an image from it accepted for publication in an architecture magazine - who can be pretty demanding. Lens is 24-90mm equiv f.2-3.3, which seems pretty fast for a compact, so you can even get a bit of control over depth of field. RAW is proprietary rather than dng, though - but you can change that through Lightroom.
The Leica suited me over the Panasonic version as I didn't already have Lightroom - and I like the overall package and accessories Leica do for it. Panasonic is functionally the same camera, though.
It has an EVF accessory which is fairly low resolution, but actually perfectly usable - I have one, but find I rarely use it, as the rear screen is excellent. A separate (optical?) viewfinder may be the most difficult bit of your spec. If you compromise on that you can access a lot of ability in good compacts now. You may not miss your DSLR much at all!
I mostly use the ever-ready case, as I usually carry a shoulder bag with me in the pannier of my nice old BMW, but the camera can comfortably fit in the pocket of my motorcycle jacket in a soft case.
I find it's main weakness for motorcycle touring is the lack of a car charger - but presumably some far-eastern enterpise will bring one out shortly (I hope!).
I'd say this one is worth a look - and there are others in this field also worth examining.
