OK, that should be possible.  However, ISTR that MTA timeouts tend to
be REALLY long, so probably you need to lower exim's timeout for that
operation.  I doubt it defaults to temporary reject on filter timeout,
because if it's an infloop or something like that it could get
ugly---all of your SA childs could be tied up processing retries that
you (should ;) know will fail in the same way.  "Can we spell 'DoS
yourself', children?  I knew you could!"

[You may have a pretty good idea what you're doing here, but you see
the potential if the package defaults to "temporary reject", right?]
