It's a cool idea in premise, the problem is that every account is allowed what GM's will call "mulligans". Although they will never tell you how many item/character/pet restorations you are allowed to have (because its not noted in the TOS) the usual guideline is 3 mulligans (sometimes 4 in extenuating circumstances) within a 6 month period AND they can see when your last ticket was and what it was about.
I'm sure it's cool if there's one or two pieces you need but space the tickets out a bit and if you go for a whole set, remember that "Defrauding a GM" IS in the the TOS and will get you a 72 hour ban and marks against your account that if banned again can result in account termination.
