Not really... The way to do this would be to change dbus (something always running in the background that carries messages from one application to another) to make it think that com.nokia.Tear (Tear's dbus service name) is actually com.nokia.browser (the official browser's service name). People have brought up the idea of doing this, but there's a small problem: Tear doesn't respond to the same messages the official browser does. Even if it did, there's no guarantee it would work.

Bundyo: If I filed a bug for Tear to also respond to new_window, is there a possibility of you implementing this? I'm not even sure if it would be possible even if Tear did respond to new_window, but it's worth a shot. Maybe I'll boot into Ubuntu later to try to compile Tear with this modification...
