Honestly, if I were just doing on-walls flanking a wall-mounted flat panel, I would only be looking at L & R anyway.

I don't see a need for a center when the L & R are only separated by the width of a screen, unless, as was said, surrounds and a sub are being added as well for a full HT experience.
