https://www.newcaliforniastate.com/ There will be some background here. Remember, if TX leaves they will have no military. I know I know muh Texas but in reality even your natty guard is Federally funded. Mexico, backed by China will take you since you will have no allies. Remember that shit. Im not wrong. A better plan would be to try to get most of the US COUNTIES to join you in abandoning the US in its current form. look at the county election map. This is the real map of the US. This would give you upwards of 90% of the land-area. It will give you all of the important resources minus the ports and cities. Then a simple siege of those cities would be possible.
