This is actually a great idea. Back in the early days of photo-journalism...it was quite common to have a dual-camera setup for PJs. Or even 3 lenses (35, 50, 90), and just switch between the two. The benefits were multiple: better, simpler prime optics. But also it turns out that most people develop a keener eye. Zoom lenses suffer to some extent from ~infinite degrees of freedom, which inhibit to some extent developing a good 'eye' for how each focal length distors reality from a 3d to 2d transition. So, by adopting dual optics...perhaps we can see faster, simpler and higher quality glass without the loss of practicality. Shooting portraits with 28s isn't always flattering, and shooting Landscapes with 90's can be equally frustrating.
