You can't really tamper with the body of a message in a system filter.

Either

(a) You could do all local deliveries by piping to some program or
script which did what you want. You would have to take care to do your
own mailbox looking, or alternatively pass the message back to Exim,
flagged in some way, for delivery. This is rather like some
virus-checking schemes that people have set up. See FAQ Q0823.

(b) You could write a transport filter for the local delivery transport.
