I'm trying to send multiple Via's from SIPP:

Via: SIP/2.0/[transport] [local_ip]:[local_port];branch=[branch]
Via:  SIP/2.0/[transport] [local_ip]:5080;branch=[branch]

However, this approach doesn't work. What is the correct syntax to achieve this?

I tried exactly as you said and it worked. Maybe your problem is not in this specific part. In my test, I sent this message:

  INVITE sip:[service]@[remote_ip]:[remote_port] SIP/2.0
  Via: SIP/2.0/[transport] [local_ip]:[local_port];branch=[branch]
  Via:  SIP/2.0/[transport] [local_ip]:5080;branch=[branch]
  From: sipp <sip:sipp@[local_ip]:[local_port]>;tag=[call_number]
  To: sut <sip:[service]@[remote_ip]:[remote_port]>
  Call-ID: [call_id]
  CSeq: 1 INVITE
  Contact: sip:sipp@[local_ip]:[local_port]
  Max-Forwards: 70
