Are you suggesting a change of destination now, when there is no info about any cancellation? That is hardly going to work.

Once the flight is cancelled, AY might be more keen on listening and if you're content with flying to HND and continuing on your own from there, I am sure they would agree.

To change the destination sort of proactively is also kind of a lottery – you could very well end up with HND cancelled on your day of travel.
