Ferrari are prone to rash decisions, but Vettel out, Charles and Kimi (whilst i appreciate giving Kimi 100% number 1 backing would be interesting) seems a step too far.
Firstly, its not cheap to pay off a multiple WC, Kimi has, realistically, 2 years max left at the top, and Charles is still a risk, although undoubtedly quality.
Actually, the more I think about it, I am talking myself into it being a good thing for Ferrari!
Kimi helps Charles get his head on straight in Ferrari, then steps aside in 2020 or 21 to give Charles the reigns. Only thing is, keeping Vettel to the end of his contract, and dumping Kimi seems a lot cheaper and less hassle.
