I should know by now that declaring something impossible in LilyPond
is unwise. :)
It is possible to generate a percent repeat for the first bar; all you
have to do is create an explicit PercentEvent (which usually comes
from the iterator):
forcePercent =
#(define-music-function (parser location mus) (ly:music?)
"Create a percent repeat the same length as MUS, labelled `1' if
countPercentRepeats is set."
(let ((percent (make-music 'PercentEvent
'repeat-count 1
'length (ly:music-length mus))))
(make-event-chord (list percent))))

\context Voice = "foo" {
\clef bass
c4 r g r
c4 r g r
c4 r g r
c4 r g r
}
\context Voice = "foo" {
\set countPercentRepeats = ##t
\override PercentRepeat #'transparent = ##t
\override PercentRepeatCounter #'staff-padding = #1
\repeat percent 4 { \forcePercent s1 }
}

It should be quite simple to implement: the basic code for centring is
already there for full-bar rests and percents.
