rest height

[Jeff Henrikson]

Is there a way to change the vertical height of a rest symbol?  Eg, this top 
half of a drumset part looks really funny with the
rests mid-staff:

        % 12/8 time
        \context Voice = HANDS {
        \property Voice.verticalDirection = \up
        <
        \context Thread = RIDE {
                \property Thread.noteHeadStyle = "cross"
                b4 b4 b8 b8 r8 b8 r8 b8 r8 b8
        }
        \context Thread = CLICK {
                \property Thread.noteHeadStyle = "cross"
                s4 e4 s4 s4. e4
        }
        \context Thread = TOMS {
                \property Thread.noteHeadStyle = ""
                s2 g8 g8
        }
        >
        }

Thanks in advance,
