IIRC, AMD's model for chiplets could already combine x86 and ARM as an example, not sure if any such beasts are in existence, but should be possible.

Yeah, I'm actually thinking something like a socket integrator buying an 8 core chiplet from AMD or Intel to connect via CXL or whatever to the ARM/RISC-V/GPU/Tensor cores in the other chiplets from different manufacturers.
