Do

   (get 'adwaita 'theme-settings)

and collect all the face settings in the resulting list.  Each list
element should have the form

   (theme-face FACE adwaita SPEC)

where FACE is a face which is customized by the theme, and SPEC is the
face spec specified.  Once you know FACE, you probably want to

  (face-spec-choose (face-default-spec FACE)

to get the face attributes for the face's default (uncustomized,
unthemed) face spec, on the selected frame.  Then you can put that
attribute in face-remapping-alist.
