You could hold the model internally and just update the QListView whenever the 
user requests by clearing it and adding the appropriate items.  Kind of 
simulating model/view if that makes sense.

You could also maintain two different listviews and use a QWidgetStack to 
switch between them, though that's probably much more trouble than it's 
worth.

You could do the in-place editing on the QListView without trying to replace 
it afterwards.

And finally, it may just be quicker (seriously) to simply re-create from the 
data source than doing a tree-walk.  It depends on the data source and the 
algorithm of course.
