Realistically speaking and in my personal view, there are only two ways for Kodak to go with still film production: One, to down-scale significantly as the demand today does not justify the capacity of the coating plant. Two, license the coating to another operation which can make it profitable, whilst keeping, say, the final quality control and branding in house.
I read an interview long time ago with Mr. Maitani, the designer of the Olympus OM series. He explained that at the end of the series in the 90'ies, the whole production line, tooling etc. had to be dismantled and sold as scrap to recover at least something because at the capacity it had, if run even for a few weeks at full speed, it would cover the market demand for a year. Considering that starting up and shutting down a complex production line takes some serious planning and doing and that letting it "idle" is not an option, it became a simple decision governed by practicalities. The nail in the coffin during the interview was when the reporter asked him to confirm if, for this reason, there would never again be an OM series camera body built again and Mr. Maitani dryly replied "That's right. Never again.". Just like that. End of story.
