I highly doubt it.
People have been saying that the US dollar will become less of a reserve currency globally for decades now. And its status has simply not changed. And it's not going to until there is a system reset worldwide where all fiat depreciate in value.
In that instance, I don't think that the replacement would be any other fiat currency either, no matter how strong their economy may be. It is almost guaranteed to be a cryptocurrency, and BTC is the most obvious candidate at the moment.
I mean look at what it took for the US to take over Pound Sterling of Great Britain and replace it with The United States Dollar, a world war and an entire people were at risk in the making of that. That is some serious SH#^$&* for that to happen. The thing that is backing the US mostly is the military , which ours is like 10 times larger than the next? idk but its bigger by a decent margin than any other country for sure....
