Imagine it: getting to see all that managed mischief firsthand instead of from the sidelines or in dialogue summary afterward! Would one of them be the Chosen One in my scenario? I don't know; perhaps. If they were the focus of the series, that might be inevitable. Maybe it would also be good to turn one into a girl, to balance things out, while not losing any of the mischievous cheer.
This would of course make a certain event in book 7 all the more heartbreaking if it still took place as written. Then again, if it were up to me and my comedic bent, I probably wouldn't allow that. Dumbledore and the swirly dream-state between life and death would send that troublemaker right back again to the living.
* I kind of wanted to write " Marauders' " rather than "Marauder's," because it was originally created and used by four marauders. But it does say "Marauder's," and I guess the singular works, in the sense of "any interested and qualified marauder."
