Hmm... you could draw the "x" stencil directly using Scheme, which would
give you some more control over its appearance (line thickness, size).  But
it looks like that in itself does not position it automatically where you
want it.

If you're running 2.19.2 you can use "make-path-stencil" to do this, as
shown below.  In 2.18 there are these two other options shown in these
snippets:
http://lsr.di.unimi.it/LSR/Item?id=623
http://lsr.di.unimi.it/LSR/Item?id=891

Below I've used ly:stencil-translate to move the "x" to the right manually
by 0.65  (If you change that to 0 you'll see where it's placed by default,
centered on the right edge of the notehead.)  Maybe there is a way to find
out exactly how far over LilyPond places dots relative to the notehead?  I'm
not sure how though...

Cheers,
-Paul


\version "2.19.2"

x-stencil =
#(ly:stencil-translate
  ;; draw the x with make-path-stencil
  (make-path-stencil
   '(moveto -0.3 -0.3
      lineto 0.3 0.3
      moveto -0.3 0.3
      lineto 0.3 -0.3 )
   ;; the "0.15" below is the line thickness
   ;; the "1 1" scale the stencil on x and y coordinates respectively
   ;; the "#f" indicates the stencil is not filled
   0.15 1 1 #f)
  ;; move the x to the right, using ly:stencil-translate
  (cons 0.65 0))
