Mirrorless lenses are only smaller when it comes to ultra-wide to wide-angle lenses. All the rest is essentially as big as comparable DSLR lenses of the same format. Mirrorless cameras are smaller, of course.
A mirrorless camera with EF mount seems really very stupid. The achievable size advantages would all be gone. The "empty deep hole" serves no purpose. An adapter solution would be "good enough" for keeping EF compatibility really. If they really chose EF for their mirrorless camera it will hurt them on the long term.
Pentax tried to do that with the K-01 if you remember that one. It failed miserably.
Also - only STM lenses are aligned for serious use on a mirrorless camera. USM lenses will be a compromise at best in terms of AF performance.
