If we are talking about the Writable aspect of this, then whatever input format we use should reasonably be able to handle both kinds of data with the conversions as you suggest.
For algorithms that are accepting arguments of a particular type, it might be reasonable to let NVW extend VW (I am not at all sure about the unintended consequences of this, but it sounds plausible). Then all we need is a facade that exposes an NVW interface for a wrapped VectorWritable with some kind of default labels (say the indexes as strings).
