No... Just stop please.
1. Minato doesn't have the chains, he's not, nor was he ever a jinchuriki.
2. Bijuu take less than 16, as the Sanbi was found by Tobi and Deidara. I would imagine its been there for a while. It's likey less than 10 years, I'm only using 16 to give you a guide as to when it came back.
3. It takes a lot of chakra to teleport something like Kurama. First, he would have to fight Tobi, again. Fair enough, easy difficulty. Not only then, he would have to teleport Kurama far enough, so he can't actually just walk back there in 30 seconds. You're forgetting how huge he is. That far of a teleportation is enough to starve Minato of chakra thus killing him. He was winded after teleporting him, what, a mile?
4. Sure, he could have came back for him as a child, but which baby was Naruto? The kid without his fathers surename? Yeah, just kill every baby in the village
