That is the desire. (Or use your Discover Card to buy $1,500 of Target Gift Cards, because Oct-Dec is 5% cashback on Discover at Target/Amazon; so same discount as Red Card.) The issue is if you can still buy Disney Gift Cards (which are considered prepaid entertainment cards by Target) or if they have closed that loophole. In the past many people (myself included) have purchased the Disney cards with Target gift cards. We've been hearing reports of people saying that they were unable to do that now, and a few people saying that they were still able to do it. However, there are also people who were getting confused with purchasing Disney gift cards with their Target Red Card store credit card and getting the standard 5% discount for using the Red Card (which is still allowed) and purchasing Disney gift cards with Target GIFT cards.
I guess the good (or bad, depending on how you look at it) thing for my household is if we buy ~$1,500 of target giftcards at 10% off and they won't let us buy Disney Gift cards, we'll still spend this amount in target over the next few months and can just apply to other purchases.
