Suggestions on gear

The lenses that I have right now are 17mm/25mm/45mm f.8 Olympus lenses, the 40-150 kit lens and the 12-40 f2.8 pro zoom. I am quite happy with these lenses. Maybe add a wide angle or macro later on.

The E-M1 is small compared to my old Canon 40D. However, it still feels handful in some occasions. So, I started looking into a 2nd camera that I can take with me more often.

I think your quest boils down to that bit. Seems like you're looking for a small photo kit for everyday carry. You've had some nice compacts and some nice, smaller MFT bodies in your hands.

I see a few options, with little-to-no need to buy anything.

Carry one of the compacts and leave your MFT gear behind unless you believe there's a possibility for something out of the ordinary that day. Figure out which compact best meets your needs, and let the others go.

Carry your E-M1 solely with the 12-40. That's a balanced package, and your 40-150 would complement it well if you want something longer in the bag. It's a great lens that nearly covers the FL range of all of your primes. Unless there's a specific quality about those primes that gives them a significant edge over the 12-40, there's no need to carry any of them.

Carry one of the smaller MFT bodies with the 12-40 (might be a little awkward & large) or some of your primes. Again, bring the little 40-150 along, if desired. If you want a WA, the Olympus 9-18 is quite small, and would fit well with some of your little primes. If you don't mind lens changes and want the smallest MFT ILC combo in your hands, primes are the only way to go.

Carry a small MFT body or E-M1 with one prime lens. Even the E-M1 becomes a small camera with a little lens mounted, and you have a few to choose from already. The "normal" 25mm lens would be a safe bet. I used to carry my E-PL1 + Panasonic 20mm f/1.7 and was happy with what that combination offered. If you decided that WA was more to your liking, the Olympus 9-18 would again be a good choice for a single lens, but only if brightness wasn't a major concern.

Another question that I don't believe was answered: how do you plan to carry whatever you decide on? Bags, clips, packs, etc. all can have an impact on what you may decide makes the right everyday kit for you.
