Have fun scouting for crazy proposed propositions, if you want.
In answe to your question, somebody has apparently submitted three initiatives surrounding healthcare and is collecting signatures, but I can't see any information on the three so they obviously won't actually be on the ballot.
Unfortunately most propositions that actually reach the ballot in practice in most states are one of these options:
A) weird symbolic crap "recognise the state will NEVER bow to the Canadians"
B) feel-good stuff like "Veterans with only one arm should have ten percent off their Netflix sub!" or otherwise populist guff.
C) u controversial attempts to fix the spelling and grammar of the constitution, that is only on the ballot as a formality.
This one is probably the best:
