How would you market make an equal weight S&P ETF outside U.S (NYSE/NASDAQ/S&P500) trading hours?

My question is : How would you market make an equal weight s&p ETF outside us trading hours?
Knowing that this particular ETF is a tracker of the S&P 500.
Would you check and see which of the underlying assets are cross-listed? And see at which Net Asset Value/stock price they trade on other exchanges outside the US? So that you have an idea of what price it will probably have when the US market opens again. Since it is equal weight, should you check all funds of the S&P500 and check all other possible listings on other exchanges?
If you can not find them then you should find a company with a same correlation?

Curious what some people with a little more experience find about this argumentation.

Thanks in advance for every input.
