The keys could even be pre generated whenever cycles aren't used to
speed up the process (this is most probably a better solution). We
would then have machines that can generate identical OTP keys given a
synchronization cue based on an initial machine state.

That's not a OTP. Shannon's proof of security of the OTP does not apply to your proposal. You've got a stream cipher, at best.
