12" and under would remind me of my background light stand with a ballhead on top. Unfortunetly you can't lower it tho. My current light small tripod is a Slik Sprint Pro. I like it for 35mm but you would have to cut down the column. Outside of that try the Bogen Manfrotto table top tripod. From what i remember it seemed pretty sturdy had had a pretty wide base which you would need.
