Sql-server – In SQL Server 2008, is possible to one database subscribe 2 publications for the same database? (merge replication)

I'm trying to set up an high availability architecture using merge replication.
I have 3 databases, and I'm trying to keep them all up to date with merge replication.

So far I've manage to create one publisher and 2 subscribers, and all works fine…except when the publisher goes down.

So I thought about creating one more publisher and make the other databases also subscribe to it. I can do the publication normally, but when I create the local subscription, even though the GUI says it went successfully, the new subscription does not appear under "Local Subscriptions" folder.

Is this possible? or is it a limitation of sql server? (if it is possible…what may be wrong in my setup?)

regards
