You'd rather have to modify the function that computes the first system
position on page: `first-line-position' in the file
scm/layout-page-layout.scm

;; not tested
(define (first-line-position line layout)
  "Position of the first line on page"
  (max (+ (if (ly:prob-property? line 'is-title)
              0.0 ; do not use page-top-space when the 1st line is a title
              (ly:output-def-lookup layout 'page-top-space))
          (interval-end (paper-system-staff-extents line)))
       (interval-end (paper-system-extent line Y))))
