I think we should also look at modifying some other amendments have lead to the current chaos.
16th amendment re: income taxes
19th amendment re: women voting
26th amendment re: 18 year olds voting

Don’t forget the 17th: direct election of US senators, which has done incalculable damage to state sovereignty
