For now I am going to stick with what i've got, suck it up and lug the K-5ii around as much as I can. I took it out last weekend when I took my son to the playground and I got some amazing shots. One thing that was hugely beneficial was my sling strap (OpTech Super Classic Strap Uni Loop) because it's easy to sling the camera snug to the side and still chase around a 3 year old without having the camera float everywhere.
When Black Friday comes, i'm still going to keep my eyes out for a Sony RX100 II/III and pull the trigger on one if there's an amazing deal that's too good to pass up, but I feel it best to keep my K-5ii for the bulk of my shooting as I can't see myself parting with it
