Nope. The ceiling is the worst possible location for speakers, except maybe for surrounds. But even surrounds are better being mounted lower, preferably just a few feet above ear level. Mains should be nearly the same height as ear level.
There are very few sounds that naturally come from above. Most all sounds are generated by things at or near ground level, so the most realistic illusion is created when the main speakers are at this height too. Again, the only exception is surrounds, which do work best being above the listeners - but not overhead - to the sides (for five channel) and sometimes also behind (for seven channel).
