Agreed - tens of thousands at least... and then what? What is there to make that hasn't been made already that can make up for that huge financial risk?
I get that some people want some things re-made but I don't think there would be enough sales to justify the cost to a company.
Plus there are no movies that interest me currently. I'm not sure about in the future, but lately marvel movies have fallen flat for me. I know I don't speak for everyone, but even with a fairly large obsession with collecting, there's nothing that I really want that's new anymore. There's nothing iconic, like the start of the marvel movies, captain america's shield, thor's hammer,...etc., where other companies haven't already made ten billion versions of the same thing.
