when I was writing the "double" function, I was heavily improvising because
I didn't yet know the \overlay command (or it was not available in older
LilyPond versions).
A more reliable way would now be:
% ----------------------------------------------------------------
#(define-markup-command (double layout props letter)
(markup?)
(interpret-markup layout props
#{
\markup{
\overlay {
$letter
\translate-scaled #'(0.4 . -0.4)
$letter
}
}
#}))
% ----------------------------------------------------------------
The pair of numbers after \translate-scaled exactly defines the shift of the
additional letter.
If you don't want additional parameters for the "\double" function, maybe
the use of properties might be an option:

I never tried that, but it looks interesting.
Does that help?
Cheers,
Klaus
