 Yes, sir. God cannot die, as you actually said earlier. But God can also do anything he wants to do, including take on flesh and be 100% man and still not cease to be God. So he had to die in our place to pay for our sins. God couldn't die, so he takes on flesh as a man. Nor can a man endure the wrath of God, because that is what it means when he says that he poured out his wrath on his own sons.
