I cannot figure out at all what the original poster wants.  If your
proposal is in any way going in the direction he is aiming for, chances
are that

\layout {
  \context { \Staff
    \name "HiddenStaff"
    \alias "Staff"
    \RemoveAllEmptyStaves
  }
  \inherit-acceptability HiddenStaff Staff
}

will do what he wants with regard to an additional HiddenStaff context
(though I have no idea why one would use that name, and one may want to
do the same for \midi though without \RemoveAllEmptyStaves in order to
not have the Midi production confused by HiddenStaff).
