Yes. What I have in mind, however, (as I mentioned already ealier) is some general adapter class template<typename T, typename Index, typename Policy> struct array_index_adapter { ... }; that can apply different types of indices (row major, column major, triangular ...) to different containers (stack allocated, heap allocated, mixed like boost::small_vector etc).
