I think what you may be unaware of TDS is that everyone starts out with ideas, but it’s important to measure those against practicality. As a rule, it’s found that most of the work gets done here by people deciding ‘I’m going to do that myself’ rather than ‘Can someone else make this idea work?’ There are lots of free programs, and free teaching, that people use to realise their ideas, and they are accessible to people without any experience - the vast majority of us here are not professionals and had no or minimal experience in any of the fan editing disciplines before embarking on our projects. Similarly, at this point, the vast majority of ideas that can be had about especially the earlier movies have been had already, and more radical ones (like replace a character) are still outwith practicality. I’d recommend reading through the ideas threads, and the threads for the most successful projects, to see what the process looks like, and help refine your vision, and then consider picking up one of the tools required to realise it.
