Since the dynamic's X-parent is the notehead, you can normalize its
position by retrieving the notehead's Y-offset:

dynamicsAllInside = #(define-music-function (parser location offsetX shiftY)
(number? number?)
#{
  \once \override DynamicText #'X-offset = $offsetX
%   \once \override DynamicLineSpanner #'Y-offset = #0
  \once \override DynamicText #'Y-extent = #(cons 1 -1)
  \once \override DynamicLineSpanner #'Y-extent = #(cons 1 -1)
  \once \override DynamicText #'Y-offset =
    $(lambda (grob)
       (let* ((head (ly:grob-parent grob X))
              (offset (ly:grob-property head 'Y-offset)))
         (- (/ shiftY 2) offset 0.75)))
#})

Neil
