Two center speaker arrangement would be best in your case, because of the fact that the center speaker is on it's side and the drivers are not aligned vertically. However, by putting the two speakers on their sides in a mirror image arrangement with the top tweeters of the two speakers next to each other, the vertical misalignment will be neutralized.
