I guess my question is: Why would you do this if you're not interested in getting the Centurion and not interested in the MR points???
It's a lot of effort and many possible negative actions can be taken against you for something that you don't seem to care about.
But, anyway, as one poster mentioned, it doesn't matter if your customer would let you do it, if your bank would have a problem with it or not.... AMEX will put you under a FR in about a month (honestly, probably a week) if you start hammering your card with tens of thousands of dollars in electronics. Then, no matter if you're paying off your card every month or not (or making payments during your billing period), they'll cut your limit down once they verify your income and bank account balances.
So, no matter what other problems you may or may not have, AMEX won't let this happen.
