Modify it slightly:
1) Take insurance on small hands but only if the previous two dealer Aces were NOT blackjacks. Rational: It'll make you look like a ploppy by calling upon the Something Is Due fallacy, but it'll only cost you about 1/3 of the cost of taking insurance all the time. Also, taking insurance all the time is A Sound And Thought Out Plan. Ploppies don't have those. They play hand-by-hand, and by gut. You don't want to go in always taking insurance. You want to go in with a quasi-mystic, incomprehensible reasoning for doing something one time and not another.
2) Rather than stand on all your 16s-- agonize over the decision, and then make a random choice. Base it on anything you desire-- gut, coin flip, if the waitress in on your left or right side, what the previous 16's results were. Or interact with other people. Ask the dealer for his advice. Ask 3rd base what he'd prefer in order to maximize the potential of the flow. If you're going to act like an indecisive, knowledgless helpless ploppy, then damn well ACT like it.
Both these techniques employ the wrong decision, but in such a way that it allows you to make the correct decision as well without looking suspicious.
Oh, and ramp up the act doubletime when the pit is actually watching. That's your audience.
