Currently have a provider / consumer setup in one datacenter. Looking to expand to other datacentre and would like better redundancy.

Do not move to multi-master until you upgrade to a current OpenLDAP release. I also strongly advise using delta-syncrepl based MMR.
What's the best way to change from provider / consumer to n-way master? Down time is an option.
Can the current replication be stopped, reconfigured and then started again?
You can do it with zero downtime.
https://github.com/Zimbra-Community/zimbra-sources/blob/master/main/ZimbraServer/src/libexec/zmldappromote-replica-mmr is a script I wrote to promote Zimbra replicas to be part of a MMR node. You would of course have to adapt it to your environment.
