Possible ways Provision objects to Connector space in FIM.

I have two SQL databases and Management agents for both.

I need to Provision my object (person object to be specific) created in SQL-1 to Connector Space of SQL-2 MA. I have a rule extension .dll which suffice my purpose. 

I don't want to use FIM portal to configure Sync rules. Are there any other possible ways to provision my objects to all the different connector spaces of connected External Source.

Thanks in advance :)
