“Better idea:
Have your state pass an amendment repealing the 16th amendment”
It doesn’t work that way. A state may not originate the amendment process. It has to come from the congress or from a convention.
What convention originated the ERA amendment that passed in so many states?
No, the State's start the process, Congress has to call it by law (Constitution), but haven't in the past. The GOP does control congress (somewhat), and we have hot potato IRS issue now working for us. Perhaps opportunity is knocking...
