This works very nicely, except for one oddity: the note heads
and slur and tie marks are not positioned quite right with 
respect to each other. 

Try this, for example: 

melody = \notes \relative c''
        {
        \property Voice.stemLength = 0
        g4()a g()f 
        \slurdotted 
        g a()g 
        \slurnormal 
        c()c g()a b( a 
        \slurdotted 
        )g  
        ()g \bar "|." ;
        }
nulltext = \lyrics { "" "" "" "" "" "" "" ""} 
latintext = \lyrics {
        Glo2 __ ri __ a4 in ex- cel2 __ sis     de2. __  o
        }
englishtext = \lyrics {
        Glo2 __ ry     be4 to2  God    on     high1 
        }
\score 
        {
        \simultaneous
                {
                \addlyrics
                \context Staff = mel
                  
                        {
                        \cadenza 1;
                        \melody
                        }
                \context Lyrics \nulltext
                \context Lyrics \englishtext
                \context Lyrics \nulltext
                \context Lyrics \latintext
                }
        \paper 
                {
                \translator 
                        {
                        \VoiceContext 
                          \remove "Stem_engraver";
                        }
                }
        }

I'm assuming this is because the slurs are positioned
where the notes heads are expected to end up, but Stem_engraver
is no longer around to put them there. 

Is there an obvious solution that I'm overlooking? Many 
apologies if so. And thanks in advance.
