hi Ståle,

personally i'd go with the second idea. this part of the notation manual 
concerns staff modification: 
http://lilypond.org/doc/v2.18/Documentation/notation/modifying-single-staves

the main tricky part is modifying the Clef stencil, which can be done 
using a markup:

{
  \override Staff.StaffSymbol.line-count = #11
  \override Staff.Clef.stencil = #ly:text-interface::print
  \override Staff.Clef.text =
    \markup
      \combine
        \raise #2 \musicglyph #"clefs.G"
        \lower #2 \musicglyph #"clefs.F"
  \clef alto
  c'1
}
