If you don't need the custom fonts, then just use the form tools in
Acrobat Professional to change the font on the form field to one of
the "Base 14" that don't require embedding for use in form fields
(Helvetica, Courier or Times). Then do a "Save As" and the font
will be removed.

A very interesting case, but unfortunately, there is no way for
Acrobat/Reader to know that about your fields - and so it requires
the entire font. In addition, since it's doing actual editing, it
wants a variety of font data to improve the layout quality. This
data exists when fully embedded but is removed in a subset (such as
kerning tables, OTF layout tables, etc.)
