If you make changes to the ticket after flying the first leg and change the routing or stopover points, you shouldn't be charged. CX might try, of course, but it all depends on the agent and how often you're willing to HUCB and push the issue.
For clarity, in option 2 they should be charged the $125 fee for changes to ticketed points in that scenario, but not a complete reprice. And they'll be dealing with AA as the ticketing airline, it's just on the CX fare basis (from how I read the post).
Having said that CX just changed one for me last week (CX issued ticket) for free when I did change ticketed points, but I believe my taxes and fees actually went down in the change, so was probably a wash or nearly so. I changed from a CX transit in HKG to a MH / JL transit in KUL, from what I can see KUL has no passenger or facility charges for transit, while HKG has a fairly substantial one. I'm not sure about YR, but since it's a CX ticket I suspect I also saved a bit there changing from their codes to MH and JL.
