Well you could add some x86 specific extensions to RISC-V to significantly speed up x86 emulation?

If you're using x86 cores to run the code, it's not really emulation.

If you're intel or AMD, you can add a x86 mode to your RISC-V processor.

Even a hardware-based x86 frontend. It could e.g. run usermode code uninterrupted, escaping to RISC-V on syscalls, interrupts, exceptions.
