Can I seize FSMO Roles if my Root/Parent Domain Controller Died and my Child Domain Controllers are still operational

Good afternoon-

I have one Root Domain Controller (root.com) that just died physically and cannot be repaired - The Root DC had the Schema Role on it, So now when I try to modify group policies, I get an error indicating that no domains are available. I also have Child Domain Controllers (child.root.com)....I wanted to know can I seize roles from the dead Root Domain Controller to a Child Domain controller without mucking up AD, Replication, etc.....?? I have a bunch of errors in event viewer in reference to the Root Domain Controller being unreachable, However, no issues with loging into the network.
