I wouldn't be surprised if Intel adds ARM support, but they might not implement the entire ISA. Instead, they could just implement some of the commonly used instructions, as a x86ARM extension similar to SSE or their virtualization acceleration hardware. Then maybe you'd have an emulator program that would run the ARM programs, and it could translate some of the rarer instructions to x86 while using native x86ARM instructions for the majority.
