This seems like a fun concept, editing together all the reinterpretations to make it look and flow like a modern film. My only advice would be maybe use the original crawl instead of the Episode IV one? I feel like the cold open intro makes it feel more like a standalone film. The Episode IV subtitle is a little jarring after that opening. The 1977 crawl would flow much better right after it I think.
Keep up the good work though, this is a very fun and interesting one indeed.
