First comic to do this?

After almost 600 pages my webcomic retcon has revealed a new secret. It can be read two different ways. The original series is a Time hopping adventure about Time travelers using superheroes to fix a broken timeline and the new webtoons version which will tell the same story but in chronological order. I had this planned from the beginning so hopefully it makes sense both ways. I don't know if anybody's ever done something like this at this scale
