No.  Spammers operate by taking a list of email addresses, and one of
those addresses gets to be the "sender."  The sendmail from, reply-to,
and From headers are all taken from this list, as well as being the
list of recipients.  If you're going to bounce it, do it at the MTA
level and, if possible, have your MTA send back at least the headers
of the message causing the bounce response, so the victim has a chance
of reporting this "joe job."

nntp://news.spamcop.net/spamcop has pretty deep archives with multiple
instances of the readership getting victimised by spammers in this
manner, as well as the occasional URL to press sources mentioning this
problem as well.

The spammer won't see the bounces, and won't get thier servers filled
up with bounce messages.

Spammers don't care if mail bounces, though.  This is well documented
on spamcop* and NANAE.
