I made this its own thread in case anyone had a question specific to this scenario. Thanks for sharing!

As far as credit history goes, I think that "age of credit" goes by whether the card is active or not. For instance, I first opened a credit card 6 years ago, but I cancelled that card 3 years ago, but I still get credit for the full 6 years. The limit is probably your biggest issue, but you may be able to work something out with your other issuers.
