Interesting project! I did a quick google to see if I could find something to add to the list. I found these, but I can’t verify them.
The Fly II (1989) uses a deleted scene from the first movie: http://www.imdb.com/title/tt0097368/trivia?item=tr0699671
In Furious Seven (2015) they used deleted footage from previous films to work around the death of Paul Walker: http://www.imdb.com/title/tt2820852/trivia?item=tr2448669
