This is 2.14 stuff, right?  With 2.16, you could write

partialInline = #(define-music-function
(parser location frac mus)
(fraction? ly:music?)
#{
\set Score.measurePosition = #(ly:make-moment (- (car fraction)) (cdr
  fraction)) ,,,

and use it as

\partialInline 3/4 ...

Or you use a duration argument like \partial itself does.  That is
likely more flexible.

That does not address any of the problems you are dealing with, it is
just something convenient on the side.
