Grace note beams won't hide correctly

[Ben]

Hi all,

This is the first time I've encountered the need to hide grace note beams and/or stems. Can someone show me what I am doing wrong?

I'm attaching an image of what I am after.

Thank you!

Here is my code so far:

%%%%%%%%

\version "2.19.82"
\language "english"


\relative c'

%% This hide the beams and stems, but I only want to hide the middle notes.
{
  \omit Beam
  \omit Stem
  \appoggiatura  {
    e!8(^[

    g! c! fs bf ef bf fs c! e,!]
    df4)
  }
}


%% This hide the stems, and it's 99% there, but I can't figure out how to finish this with the correct beaming and slash.

\relative c'
{
  \appoggiatura  {
    e!8(^[

    \omit Beam
    \omit Stem
    g! c! fs bf ef bf fs c! e,!]

    df4)
  }

}
