Hardly.  The storage format is bitcoin protocol wire format, plus a
tiny header.  It is supported in multiple applications already, and is
the most efficient storage format for bitcoin protocol blocks.

You don't have to create anything on the fly, if you store blocks in
their native P2P wire protocol format.

This is a whole new client interface.  It's fun to dream this up, but
it is far outside the scope of an efficient HTTP protocol that
downloads blocks.

Your proposal is closer to a full P2P rewrite over HTTP (or a proxy thereof).
