Idk you've got to remember that when a country uses the USD as official currency, it's usually because the local currency has collapsed, due to sanctions, imperialism, incompetent and corrupt local leadership, or a combination of all of that. There's no other option at that point, because US global hegemony. At that point there's much bigger problems than a local currency, and trying to re introduce a local currency is pretty much guaranteed to fail. (See the Zimbabwean RTGS dollar from 2019-2020). Using a mix of relatively stable foreign currencies, such as the Chinese yuan, USD, Euro, currencies from more stable neigbouring countries, etc is the best option to avoid just using the USD until the underlying material causes of instability are fixed.
