David,
I have been working on a generic stato-dynamic multi-dimensional array 
that can enable something like what you propose. It uses C++11 
functionality (variadic templates and functions mainly). Please take a 
look at: https://github.com/nasosi/mdsdarray and 
https://github.com/nasosi/mdsdarray/wiki/Interface-examples.  The 
developement is slow-paced because I am working on it at the rare free 
time I have on weekends.
I am currently thinking of how to implement an appropriate iterator that 
would be SIMD friendly. In that context I am considering something 
across the lines of the interface of OpenCL and CUDA. This would work 
nicely with the C+11 new for loops as well.

If you think your proposal can build on top or even contribute to 
mdsdarray,  I can provide a version under a Boost or  MIT license.

Best,
-Nasos
