I must confess that I am surprised. Good work :-)

I think that could be a good attack. To be honest I haven't done
that much work with ASL, so I'm not sure how easy it would be
to implement anything more sophisticated than what you suggest.
The ASL code that you're hacking on was auto generated (off-line, by me)
(unless I'm mistaken). Auto generating the replacement is probably
a good idea. I can take a stab at that if you like, though time is
quite tight at the moment as I'm travelling and in meetings a lot,
so it might have to wait a week or so.
