If it's not so complex, have you considered overloading font features with
fea files? Now that Adobe has (finally!) completed a major overhaul of the
spec, including the features neeeded for arabic, that's an option.

But for your more complex needs, see the m-translate module. Maybe that
can be developed further? Note that Hans has pointed out that this is NOT
a core module and that it is preferable to fix the source beforehand.
