Dan,
I think you could add in the pinched landing area, with bunkers on both sides, but only once per course, not over and over, a la RTJ and Wilson.
A little out of the time frame, but post CBM, a Maxwell rolling green, perhaps with extended chipping areas all around.
An exagerated long and narrow or shallow and wide green (Strantz and others)
The Valley Hole (even if not occurring naturally, a la Fazio)
The Mae West Hole (out of your time frame, but after CBM)
Cape Hole with Waste Bunker instead of water
The front center bunker green (C and C)
The delayed dog leg hole (Smyers and others)
The Zig Zag fw hole (Dye and others, but dating back to the Golden Age)
the Gull Wing Green (Riv 14 and others)
Just a short list of templates I see used over and over, sometimes even in my own work.......
