The problem is that the doable to worth it ratio for Rey as Luke’s daughter isn’t very high. It’s not an idea that’s universally good enough to devote the amount of time and labor needed to pull it off. So why pursue it when there’s a better option that is 10x more possible with broader points of contribution?

Anyone can make a personal edit on that level and share it, but the vague idea alone isn’t strong or neccesssary enough to crowdsource the specifics of how to pull it off, where to start, and the talented people to do all of that labor.
