I also find it very hard to believe that Scalia, Thomas and Alito would subvert the Constitution for any reason. That is why I am adopting a “wait and see” attitude.
Did you ever consider the possibility that they may simply not think there is a serious issue here?
After all, Hillary never made an issue out of Obama's citizenship in the primaries; McCain never made an issue out of it in the general election; and neither VP Cheney nor any single member of the House or Senate raised a single objection to the certification of the electoral votes. The Supreme Court may think that if no one sees a problem, there isn't a problem.
Let me be clear: I don't know what the Supreme Court is actually thinking. All we know is they have refused each of these cases so far without a single recorded dissent. I am merely suggesting that, before you decide they are in on a fix, you consider a more innocent explanation.
