I really respect Chief Justice Moore and wish him well.
The problem starts when a county clerk somewhere in a county courthouse decides to obey the USSCt. A majority of the Alabama Supreme Court must then vote on a court order; a single federal district judge can then restrain the ALSCt, and that order is enforceable by the US Marshals service.
Does the Alabama Attorney General or superintendent of state police then take on the Marshals’ Service?
The last line of defense will be the County Sheriffs.
I believe a County Sheriff outweighs a US Marshal.
