Hi, when overriding a grob’s stencil, you have to scale the new stencil by the 
current font-size.  Something like this:

#(lambda (grob)
    (let* ((sz (ly:grob-property grob 'font-size 0.0))
           (mult (magstep sz)))
        (set! (ly:grob-property grob 'stencil) 
          (ly:stencil-scale
            myCustomStencil
            mult mult))))
