And just to clarify - even though no one here has any intention whatsoever of ever doing any of the above, of course - odometer tampering is not just a local/State problem; it's actually a federal offense, i.e. a felony.
Have you considered just leaving it registered in the state you're leaving? Maybe get a P.O. box with a permanent forwarding plan to your new CA address in place? At least until your mileage builds up enough to re-register it in CA?
Not that I'm condoning that kind of thing...
