The only market I can think of where higher prices wouldn't be as much of an issue is the server market. Imagine that. High density, Apple designed, ARM SOCs for servers. Or maybe they'll bring back Xserve.
So what you're asking is not only for them to sell their IP to 3rd parties (a business model of partners they've repeatedly crushed) but also to build out an entirely separate chip design team focused on a new market.
That’d also be consistent with their past history of trying to pick some edge for a particular market: optimized for media processing, ML, VR/AR, etc. rather than just competing with x86 for the generic workloads. I still don’t see it as a high probability but I’d expect a niche if it happens at all.
