Shrug. You can just have your acknowledger check for font-size being a
procedure and replace it by the result from the respective call.
And then you just use your originally failing code. No need to invent
yet another internal interface, just make your original code work.
If you want an interface to the internals, it can look like
\allowGrobCallback font-interface.font-size
as a context mod. Something like
allowGrobCallback =
#(define-scheme-function (parser location syms) (symbol-list?)
#{ \with { \consists #(make-engraver ...
