This would be a simple matter of drawing up some DSL for
configuration. Then we keep extending it with every feature
request and in a couple years from now we’d end up with some
informally specified bug-ridden implementation of SQL.
Joke aside, your problem can easily be solved by symlinking the
fonts you need for a document to a subdirectory. (We could
add an option to dump a list of used font files so you can script
that part.) This way you can determine precisely which files will
be embedded. Conditional font choices like you suggest would only
add another potential source of errors.
Also, if we got rid of the ban on “write18”, we could use
fontconfig instead of the database. It allows you to write rules
for matching fonts against different criteria. (E.g. I have a
personal substitution set that eliminates the ms core fonts from
about every graphical application except when they are embedded
in pdfs.) We shouldn’t reinvent the wheel when there’s lots of
other aspects that could be improved, for instance the logging
 I’m aware that fontconfig probably won’t be available on
Windows. But there should be some equivalent functionality
that other programs use when they “access system fonts”.
