Hi David,
I may have an answer to your question:
Just test this example, it does'nt need much explanation
 

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\version "2.11.34"

\paper {
#(set-paper-size "a4")
%#(set-paper-size "letter")
 line-width = 184\mm

}

            #{ \once \override Slur #'positions = #$beg-end #})
SLUREXO = #(define-music-function (parser location beg-end) (pair?)
            #{ \once \override Slur #'extra-offset = #$beg-end #})
%%%%%%%%%%%%%%%%%%%%  END DEFINITIONS

piano = \relative c'' { 
 \clef treble
 <c g'>1( <c f>1)
 \SLURHLIM #'0.0 <c g'>1( <c f>1)

}

\score {
        \new Staff = "up"  \piano

I'd better use identifiers, so I have just to adapt the values.
The first slur is normal.
The second is flat : this is the result of "height-limit" set to (0 . 0)
But it is inclined: this is to correct with "positions" : a positive value
 takes it away from the note, at left (left value) or at right (right value).
If you think it is too close to the notes, then use "extra-offset"
 to correct it: but there the left value means to the right (positive)
 or to the left (negative), and you have just to use the second value:
 positive means higher, negative lower.
When the slur is down the note it is the same but down:
 it is always the distance of the slur from the note.
