It is possible but it will lead to really really bad interop problems.
Any rewrites to SIP addresses are likely to cause dialog/transaction
matching issues. So I really discourage such attempts.

If you think you really need SIP mangling, than you need a B2BUA (see
for example www.iptel.org/aa) -- there is no other working way around it.
