Obviously with the malts I have it'll tend to be a bit more biscuity, but I think I can deal with that. Hops-wise, I think I can manage with a combination of EGK, Challenger, and Fuggle. Yeast-wise, 60F is pretty much perfect for me. I do have the Nottingham yeast, should I just go with that? Either way, thanks.
The level of Biscuity from the MO should be all right. If all you have is crystal to work with otherwise, I'd hit it with about an equal blend of 20, 60, 120 to a total of maybe 10% of the grist. 120 will give you some raisin/currant in the same ballpark as the munich; 60 gives you caramel; 20 bridges the flavor between the base malt and the other two.
I looked up Challenger and found it is a granddaughter of Norther Brewer! I'd go with straight challenger, then, to get as close as possible to the style. Hopefully it will have some of the woody/minty character for which N Brewer is known.
As for yeast, I'd make 10 gallons and pitch different yeast in each bucket

If I only had one bucket...it depends on what you want. If you want a fruitier Cal Common, use the Saflager. If you want it cleaner (to the point of blandness sometimes) and more attenuated, use the Nottingham.
