Ah, interesting. Yeah, I suppose I didn't think to search for voice following 
lines across staves. 

One issue that also came up (and that I somewhat solved) is that the notes will 
probably be sounding simultaneously. If you'll look at my script below, you'll 
see that I used "s2" instead of "r2" as a placeholder to space it out a little 
bit. Luckily, the voice follower ignores this--when I used r2 it would try to 
draw a line from the rest to the note, which is philosophically interesting but 
unfortunately wrong.

Thanks a lot for your help--here's the current script:

\version "2.12.3"

\score {
   \new StaffGroup {
   \set StaffGroup.followVoice = ##t
        
<<
   \new Staff=one {
                \override VoiceFollower #'style = #'dashed-line
                << {c'1} {s2 \change Staff = "three" b2} >> a s2 
        }

   \new Staff=two { 
                \override VoiceFollower #'style = #'dashed-line
                g'2 f' \change Staff = "one" e'1 
        }

   \new Staff=three { 
                s1 s 
        }
>>
        }
}
