AFAIK you can not add headers to the CANCEL request as they are created
by tm module based on corresponding INVITE transaction.
There are several functions in tm module to automatically generate
Reason headers:

A workaround would be stateless forwarding, then you can manipulate the
CANCEL as you like.
