So the thought was to use courser of kruphix with vizier of the menagerie. You literally are playing the top deck. Prophet of kruphix just speeds this up letting you cast until you hit a land. In theory there will only be etb creature effects and land. Any thoughts?
Vizier and Courser are both viable because they're <= 4 mana and have > 3 toughness, so they can be played reliably even if your ramp gets shut down and they pass the Bolt test (although this has become slightly less relevant in the current meta). The rest of the options you mentioned are significantly more expensive, weak to damage-based removal, or both.
I think building around Vizier and Courser could still make for a viable and interesting Ramp deck, though.
Tireless Tracker is often played with Courser as another way to keep your tank filled if you don't draw Vizier. You might enjoy 2+ copies of her. Duskwatch Recruiter could be good, too. Otherwise I think you just want a lot of ramp from the usual suspects.
Since Vizier gives you color filtering I could also see this working into some kind of a 5C aggro deck. See this thread here for some ideas.
