If the issue here is voter fatigue (which I definitely agree with), we should just stipulate several possible dates in the year to vote on all constitutional amendments so you don't have one each week. Perhaps they should coincide with whatever the next federal election is, special or regular.
My hesitation would be that sometimes constitutional amendments fixes errors or loopholes in the constitution. Perhaps require it to receive unanimous approval to be voted on the following weekend, otherwise it is sent to the next federal election.
Good thought, Talleyrand!
