Here's an idea:

overrideGrobProps =
#(define-music-function (parser location grob-name prop-list) (symbol?
cheap-list?)
   (make-sequential-music
    (map (lambda (entry)
           (make-grob-property-override grob-name (car entry) (cadr entry)))
         prop-list)))

\relative c' {
  c4 cis d des
  % apply \override to list of properties + values (not \once)
  \overrideGrobProps #'Accidental #`((color ,red) (font-size 4)
(extra-offset (1.5 . 3)))
  \overrideGrobProps #'NoteHead #'((style mensural) (duration-log 0))
  c4 cis d des
}
