From a purely personal perspective, if I arrive at a store with AdSense on it, it tends to put me off the site altogether. It giver me the impression they are not there to sell me something, but are there to get me to click on the ads. I never click on the ads, and more often will simply leave the site and not return.
However, I do understand your reasoning.
I hope it works for you.
Good luck with the experiment, and keep us updated on how it went.
