I think you've explained it very well.
I would only add a bit of a brainstorm about 'what might a person learn in Kindergarten' - perhaps after reading a book on the topic 'Junie B Jones' is funny. There is always a lot to learn in any situation even if the academic material is not it.
If she doesn't already know some of the children in advance, then I would talk to the school and ask for some names and numbers so that she can have a few playdates in advance.
If the kindy is half day, then I think your plan could work very well. Do let her know that having good behavior is key. She'll need to demonstrate 'how grown up she is' to keep her options open.
My son says about kindy: It's the fun year where they trick the children into believing that school is about having a good time.
LOL!
