Just for information's sake, lenses of this type are usually referred to as retrofocus lenses, after the name of the earliest marketed such lens.

That's as good as you can get for a camera that takes the same lenses. The problem is that the registration distance of lenses doesn't change just because you use them on a mirrorless camera, so the K-01 is about as compact as you can make a camera that takes K mount lenses.
That's why there are two different 4/3 mounts. The original one, which was made for DSLRs and the Micro 4/3 for mirrorless cameras with a smaller registration difference. You can use a 4/3 lens on a Micro 4/3 camera, but you need an adapter to make up the registration difference. Incidentally, there are also two different versions of the old M39 screw mount lenses. The more common one was for Leica rangefinder cameras, and the other was for Zenit SLR cameras (a Russian brand). The registration distance was entirely different, with the Zenit one being much larger to accommodate the mirror box in an SLR.
So the bottom line is that you will never really be able to go more compact than the K-01 with K mount lenses. To go more compact, you have to look at different mounts.
