Mailman generated messages are not processed through the
GLOBAL_PIPELINE. They are processed by VirginRunner through a hard
coded pipeline consisting of CookHeaders and ToOutgoing. VirginRunner
also sets _fasttrack = 1 in the message metadata which causes even
parts of CookHeaders to be skipped.

The actual welcome subject is hard coded in Deliverer in the
SendSubscribeAck method.

So you could (possibly conditionally) modify the subject in
Mailman/Deliverer.py or modify the pipeline in
Mailman/Queue/VirginRunner.py to include your subject munging handler.
