Actually, Alkaline batteries can have more than the rated 1.5v, just like NiMHs have more than their nominal 1.2v. You'll be fine.

Also, regulators have a drop-out voltage between 0.5v and 1v. So, you'll be at less than 12v right from the start, and will only get worse as they drain. At a cutoff of 3.3v/cell (9.9v), the output of the regulator will be closer to 9v or a little less.
