Why not get the server to send out the messages with an appropriate
envelope sender (return path) in the first place?

Replies go to addresses in the headers, not the envelope. So you can
have them different.

That won't work at all. With respect, you seem to be very confused about
the way bounce messages and system filters work.
1. In a system filter $local_part is never set (because a message may
have many recipients).
2. When $local_part is set (e.g. in routers) it is never empty - after
all, the message has to be addressed to some recipient!
3. A bounce message has an empty SENDER address.
