In the long run that's not likely, because vim isn't nearly as extensible as emacs is; thus it's unlikely that the long tail of emacs functionality exposed by spacemacs will be duplicated in vim and those exposable by spacevim.

If you want an extensible editor, use emacs. If you want a vi-like extensible editor, use spacemacs (or just evil-mode on its own). If you want a lean editor, use vim. Torturing vim (and writing tortured code to torture vim) into a simulacrum of emacs just doesn't make sense to me.
