Use a pipe transport to pipe the message into a script which removes
the relevant headers, ie everything except the Subject I think, and
then re-sends the message to bigcheese. You certainly need to get rid
of Received: , Reply-To: , Sender: , From: , and Message-Id: as that
will contain the name of the originating machine, so you might just as
well remove everything. The From: field that the script generates
should be suggestions-request or something similar.

You could maybe make the script wait a random amount of time before
re-sending the message so that there isn't an obvious correlation in
the logs between the message being received from
whinger@??? and being sent on.

Use a director with something like

senders = "*@*.bigelow.org:*@bigelow.org"

You could do that in a script -- no problem there, surely?

It sounds fairly strightforward to me unless I've missed something in
the original message.
