Well, i have a similar system planned in the matrix library that 
Boost.SIMD is extarcted from (http://nt2.sourceforge.net).
I think it's slightly out of scope for a strictly SIMD library.

Implementationwise, it is doable I think as the core library is already 
split up upon extension detection. Adding another level is easy. But I 
fear the performance won't be that great as we'll run lots of small 
scale operation when GPGPU prefer large amounts of data (hence this 
being more a model for a matrix library).
