 No, you cannot!

I can. We call it union. Subtraction is also possible. You should try to understand these simple techniques. And you should understand that your blather does not distract from the topic: The essence is that only finitely many numbers have been lost and the rest is remaining. This makes an infinite intersection.

  You can, however, create a new set with more elements.
