Would it make sense for Sony to add an UHD drive in 12 months?

I suppose they might release a PS4 Pro Slim in early 2018 that featured a UHD blu-ray drive, but physical media is only becoming ever less common. By the time 4K TVs are in enough homes for 4K blu-rays to have mattered, blu-ray discs won't matter regardless of resolution (they hardly do now).
