Based on the West Virginia precedent:

1. The North California counties can convene to declare the CA government null and void.
2. The North California counties can elect a new (alternate) CA state goverment.
3. The new (alternate) CA state goverment can set up a vote in the North counties to declare a new state made of only the North counties.
4. If the voters choose to form a new state. Trump can recognize them as a new state, and they are therefore a new state.

Is that right? That is doable.

There are no grounds -- yet -- to declare the Sacramento government null and void. Only if the Sacramento government declares it has unilaterally seceded from the Union could that claim be considered valid.

We're not there yet.
