I don't see why not. Instead, the Goddess of Trickery and Deception in my campaign frequently goes under various guises to boost her worship through deceit: it's a double-whammy since not only does she gain direct worship, but in practising the act of deceit her power increases ipso facto (yep, it's a slightly weird system).
Clerics have access to Undetectable Alignment, have Diplomacy and, with the Trickery domain, Bluff. A high level cleric with the Trickery domain could easily insidiously worm his way into a community, especially using gradualism and populism. For example, the old priest of the community could be "found" animating the dead...how convenient
. Later on, the church of the good (evil) god's power could be waning and need monetary donations to wage war against a (fictional) enemy. So long as the priest can be keep the people ignorant, scared, affectionate or a combination of the three, he can control their moods and actions with relative ease.
