The scenario described would not match with Christianity at all, the saints in heaven retain their specific identity and freedom of action, it's why it is possible for them to intercede for us. The entire 'set up' of Christian theology is that God is goodness itself, and all truth. Human beings should align themselves to God, but they do not have to. They naturally suffer because they are rejecting what is good.
The whole point of why everything has turned out the way it has and why the things are allowed that are is human free will being of utmost importance.

You know what's actually kind of similar to the scenario OP describes? Buddhism

Assuming humanity has existed at least 20-50k years, why is it that God decided to open his gates for goyim only 2000 years ago?

First assumption is wrong but even if it were true, the heavenly gates were not really open for anyone and what needed to happen for them to open was the Incarnation, so someone like Mary needed to exist. Combine that with human free will and you can imagine why it might take time
