You could theoretically, with shareholder approval, take a company private, split the share classes, and then IPO again and resell the shares to the same people. In the interim while private, some bank would be the 100% owner, with some contract saying they must re-IPO within 24 hours and resell shares for 1 cent to the original list of shareholders. And I don't see any reason you couldn't do all this on one day - you just need approval of 51% of the shareholders and the board.
