@take, your "adapting lens" would have to be a zoom lens as different lenses would require different refraction powers. This is not feasible w/o deteorating IQ. Nice idea. Won't work.
Besides, the mFT w/o "adapting lens" allows for a new generation of wide angle lenses outperforming normal SLR wide angle lenses and bring them on par with rangefinder lenses. Esp. small sensors (i.e. FT and APS-C) need them because they have smaller pixels.
