Its possible , with minato , sasuke , shisui and kushina am sure they could stop it with sasuke(indra ) bein the main stoping force behind it given that at the time he was pure nd full of love while the curse of hatred began to worm its way into the uchiha at the time , as itachi noted sasuke could probably have changed them which i believe to be true.
But that snake danzo is and would always be a problem.
If not then minato simply summon bunta on top of their shrine next time they have a meeting Lol
