Balance tunnels within load balancer pools

Is it possible to load balance tunnel replicas within a load balancer pool? I can set up one pool per tunnel address, but not change the weight of the replicas/connectors inside that address, resulting in some servers getting much more requests than others. Or is the only option to set up a new tunnel for every server?

I believe the best option here is to create a new tunnel for each and have the Load Balancer go between the tunnel origins:

The duplicate connections on the same tunnel can’t be used as granularly as individual tunnels can.
