I don't care if it makes complete sense and I don't care about what happens in the US Navy. I think it would have fun and interesting to see McCoy in command.
McCoy was in command... of sickbay. He was a Starfleet officer and was perfectly capable of giving an order and asserting his authority when he needed to, including going up against Kirk himself. We saw this many times.
But he was NOT a line officer. Putting him in the chair would've been so much fanwank.
And as we all know, fanwank only gets aired... on TNG.
