You need to use LilyPond's native stencil functions.
Check out make-connected-path-stencil (which has scale arguments) and
ly:stencil-translate. You can basically copy and paste your work into that,
changing the syntax a bit to work for Scheme.
Then feed this stencil to the \stencil command in a markup.
