Define "replayability" then, because I would understand it to mean how enjoyable it is to play the game again from start to finish.

If your alt can immediately jump to the end of the game then, by definition, you are not replaying the game.

It would boost your ability to have multiple characters at endgame, but you wouldn't have to replay anything to get there - except maybe levelling dungeons, but they're a separate element with a question of individual replayability, separate to the game as a whole.
