Not by changing the crank, no.  But yes, you can change an engine with
360-degree timing to run 0-degree timing (or vice versa) by changing the
camshafts and the ignition.  On a modern fuel-injected bike, you'd have
to change the whole engine control computer.

However, it probably wouldn't be a good idea, because an engine balanced
to run in one timing will probably vibrate very badly in the other.
