Look, most people with 9+ speed setups have their rear indexing set up perfectly or very close to it. You don't. If it's not an issue with the modifications to your RD, which might not be as straightforward as you think, then your mechanic skills are inadequate to set up 9+ speed systems. There really aren't many options here.
