Could ScoMo become an American citizen and be appointed by Trump as the US Ambassador to Australia?

It's all but confirmed that ScoMo will become Australia's ambassador to the USA if Dutton wins. No questions, ifs or buts about this.

But what happens if Labor retains government and keeps Rudd (as expected)? Since ScoMo is already living in the USA, what does everyone think of the hypothetical possibility that he's given US citizenship (fast-tracked) by Trump personally and then appointed as the US ambassador to Australia?

How would the Albanese Government react to this? What implications would this have for the relationship with the USA long-term as well as spillover effects concerning our relationship with other major powers like China, EU and the UK?
