Changing lenses is a royal pain and opens the cameras to dirt on the sensors. Changing lenses is asking accidents to happen.
I went to England last year with two e-pl5 bodies, the 12-40 and 35-100 lenses. Not tied down with a huge amount of weight and a good choice of equipment.
Almost had a mini-disaster in a car park one day when a keen-eyed person noticed I had dropped the door to the battery compartment of one of my bodies. I couldn't thank him enough.

I'm with Isabel here. Lens changes on-the-fly touring a city, etc are an accident waiting to happen. In my six years with m4/3's including a variety European and Asian destinations, two bodies, with a P-L 14-150 on the main and a 7-14 on the other, with a rarely used Panny 25/1.4 on the side, served me well, with very rare lens changes and minimal baggage.
The GH de jour (now GH4) on a cross-chest strap and the secondary/7-14 (way wider than 12mm!) with wrist strap in a beat-up old lens-down belt-holster from the Nikon film days. No swag bag per se that attracts attention. The 25mm, flash and minipod in a small day pack w/ rainjacket, water, etc, and hotel shower caps for camera rain protection, with chips and a battery or two in pack or cargo pants/shorts.
I shot a heck of a lot above 40mm in the tight little towns of France's Alsace as well a big cities like Prague and Zurich, so I think a "super-tele" such as the Oly m14-150 or the Panny 14-140 (or the sublime, but heavy 4/3 P-L 14-150 with adapter, which may be passe by now) would be a great walk-around choice for you. I rarely found the lens speed or shallow DOF limitations of my kit limiting - certainly not for the usual daylight architectural and street-scene shots, where f/6.3 seemed my sweet spot at all FL's.
