Would US Bank convert an existing Wordperks Platinum Visa to the Signature card under this promo? I'm planning on canceling mine, but if I could get the upgrade bonuses and lose the annual fee, at least for the first year, I would stick with them. I would prefer to "upgrade" (if possible) instead of apply for a new card since I've gotten a new Amex and MC in the last couple months and I don't want to ding my credit score with too many new accounts that quickly.
