I think there's a option here: there could be no replacement. The fact of the world having a singular reserve currency is not guaranteed.
A totally possible outcome is nothing really replaces the dollar as the reserve currency, and international trade is just... less efficient because of it.
If the world moves away from the dollar, I think having a singular reserve currency replace it is probably the best case scenario
