Maybe define
>>replication-source: clusterid=mysourceclusterid,sourcevmid=123
the define cluster in
/etc/pve/remoteclusters.cfg
mysourceclusterid : ip : x.X.X.X, x.X.X.X, x.X.X.X
login : xxxx
password: xxxx

mmmm, yes, indeed ! (and run the cron on target cluster)
ip=could be an ip of the cluster.
(But I think we need to connect first to this ip, and find where the vm is
located (in case of vm is moving), and reconnect to the vm node.
Don't known how to manage this first ip connect ? (do we allow to define
multiple ips if 1 host is down?)
not sure we need to define storage=.
the storage config can be done at the targetvm creation.
(we create the targetvm with same disks than source, maybe with different
storeid, but we have already all infos in disk config).
also, if something change on source vm (disk resize, new disk), I think we need
to check that,
to do a new full sync. (if we replication through incremental snapshots).
for the replication itself, if storage support it (zfs,rbd), we can manage that
with snapshots.
if storage is not supporting it, maybe use proxmox backup or qemu backup (which
allow incremental backup, and network target through nbd)

Maybe it would be easier to define replication on the target VM only? For
example,
add something like:
replication-source: ip=1.2.3.4,sourcevmid=123,storage=mystorage
