I'd try breeding them both, but I'd wait til Jan/Feb to start pairing the 2007, just to let her get bigger.
I just put my male mojave with a normal female last night for the first time (she's 1600 grams) and they already locked up!
The more I have studied it out, the more I don't necessarily think it has to start in November. Maybe if you were in Africa, where they're native, but here -- especially captive bred -- they have no idea what "home" would be like. They're native to someone's incubator and snake rack. That's what they know. They know they smell each other and want to get it on!
Just my $.02.....I'm a newbie, too, so my $.02 is probably not even worth that...
