With all the amendments proposed it will just cause total confusion as is happening now. Have a vote where you can pick only ten of the proposed amendments give several options within each. The ten that are chosen will then be discussed as to the various options. Then voted on as to which options ill be final and that should be the foundation for the new constitution.
Other amendments can be voted on at a later date but it must be kept small enough at each vote to not be totally confusing.
