As designed, it can't work. At least if maintaining infinity focus is a requirement. The big issue is the size of the adapter's cam follower.
The focus cam on an M lens extends roughly 7mm from the rear face of the lens flange. Given that at infinity the second close-range cam on the DR-Summicron extend roughly 11mm from the rear face of the flange and doesn't clear the restrictions in the m4/3rd mount, you have something less than 3mm for the total thickness (diameter if using a rotating sleeve on the follower), front to back, of the RF cam follower. In practice you probably only have about 1-1.5mm to work with and snaking the linkage out will be difficult as the register distance between the two mounts is only slightly greater than 8mm and the diameters of the two mounts are very similar.
In addition, mounting would be difficult as the attachment, as designed, can't rotate to mount and unmount unless it is completely in front of the camera. This would place the eyepiece in an unusable position too far from the eye. It would have to be a two piece affair with the adapter and a removable RF unit or it would have to have a rotating bayonet flange on the rear.
