While you can definitely do that, there is always the chance that the PCM changes could still be uncovered, and depending on who you are dealing will, a can of worms could be opened. If you're flagged in the system, there is no getting off. The OP should be aware of this.
Best bet is to get to know you local service dept, and get a feel for how they do things. If you end up breaking something for whatever reason, you're likely SOL no matter what.
