In the past, I have done this for one of my global customers by ensuring that there is some sort of VPN connectivity between the two AD forests, and then adding a secondary DNS zone for the new domain to be synced on the AADC server. The AADC server was deliberately not domain joined in this scenario.

Once the above was in place, the AADC wizard was run again, and a new ADDS connector added for the new domain. Works really well.
