Have you looked at engraver-init.ly?  It should give you an idea how
this works (see the definition for PianoStaff).

Here's a quick snippet which also demonstrates what \alias does:

\score {
  <<
    \new Staff \relative c' {
      c4 d e f
    }
    \new BlueStave \relative c' {
      % this works because we've made BlueStave an alias of Staff
      \override Staff.Clef #'color = #blue
      c4 d e f
    }
  >>
  \layout {
    \context {
      \Staff
      \name "BlueStave"
      \alias "Staff"
      \override StaffSymbol #'color = #blue
    }

    \context {
      \Score
      \accepts "BlueStave"
    }
  }
}
