I just realised - you can write your own repeat unfold! I'm no Scheme expert, 
but I managed to write this quick hack:

unfold = #(def-music-function (parser location number music) (number? 
ly:music?)
 (letrec ((ccp (lambda (n)
         (if (= 0 n) '() (cons music (ccp (- n 1)))))
  )
        )
  (make-music 'SequentialMusic
   'elements (ccp number)
 )
       )
      )

{ \unfold #7 {\grace b8 c4 d e f }  }

It's not exactly the same as \repeat unfold, and it might not be enough for 
you (it doesn't work well together with \relative).
