Why wouldn't you use the TA for the life of the ticket? Are you trying to avoid fees (I suppose it depends on your arrangement with the TA).
I would view this as if you booked with an OTA like Expedia. My experience is that the airline won't (can't?) take control of the ticket unless you are flying that day.. but even then it depends on the airport staff. This is all very hypothetical so perhaps you can share what exactly you are trying to achieve.
Re: codeshare
What do you mean by "sticks"? Sometimes the airline will discontinue codesharing on that route even though the flight is still operating.
