A fontset maps a character to a font, and a CCL encoder maps a
codepoint to another codepoint.  Actually, the variable
font-ccl-encoder-alist is used for that purpose in mac-win.el.

It may not be automatic or transparent, but customizing the default
font is as simple as

  (add-to-list
   'default-frame-alist
   `(font . ,(create-fontset-from-mac-roman-font
              "-*-FAMILY-medium-r-normal--SIZE-*-*-*-*-*-mac-roman")))

or

  $ defaults write org.gnu.Emacs Emacs.font 
'-*-FAMILY-medium-r-normal--SIZE-*-*-*-*-*-mac-roman'

and not so different from other platforms, I think.
