But I don't plan on changing anything that is in motion. My plan only involves adding something to it, not destroying something. That is why I think it is possible, because the whole WTC can be built, as it is currently planned, and there will still be empty space to build on, without compromising anything underground except a few parking spots and a bit of the museum.

Why I think this can be done? There is still some space underground to compensate the parking, and since I would turn part of my proposed twin into a memorial, some things from the museum could go in there.
