Hmmm.....

The problem Mirex had with my custom Mamiya to OM t-s adapter was the 
space for the bayonet release.  They engineered the release
to be inside the adapter.  It is a bit fussy at first but works well.  
That would save some space.  There would have to be one external 
release of course.  A glassless adapter  OM to alpha with the Mirex 
solution on the OM side seems difficult but possible.  I would bet Ian 
at Srb Griturn
as the technical advisor or SK Grimes with their machining skills might 
give it a go.

Yes, but with such a small distance, the camera's mount should be quite
_wider_ than the lens' mount, otherwise there would be no room for the
bayonet lugs:

It also mentions incompatibilities with some Zuikos as well :-( 
Definitely
not a good solution.
