Parity is in no way incompatible with ANY of the other approaches you listed. I have been VERY explicit that the US market might take time to warm to, and understand a new Australian stock they have never heard of before.
Regardless of which market drives the other one, and regardless of which market appreciates the stock more at a given time, parity was always going to be the first step. The two markets start by converging in one way or another.
I'm truly not sure you even understand what you are talking about.
