You might be able to do something like this, which adds invisible notes
that are spanned by the arpeggio:

blanknotes = { \property Thread.NoteHead  \override #'transparent  = ##t
          \property Thread.Stem  \override #'transparent = ##t }

\score {
   \notes \relative c' \context Voice {
   <b \arpeggio \context Thread = bl { \blanknotes <e g c e a> } >
   }
}

The stem length also needs shortening here, but you get the general idea.
