From the way you presented this, I'm going to assume your opponent is in FL, so you are setting without any information about what cards are live. With that in mind, I'd set this K:d:/A:h:A:c:4:d:2:c:/xxx. The goal is to catch another K on top (although if you catch a Q before you catch a K, you'd place it there, and have the chance to make either KK or QQ on top), and to make any hand that beats AA on the bottom.
Some good players might set K:d:/A:h:A:c:/4:d:2:c:, but I'm not as fond of this option because it gives you much less flexibility with the bottom hand. The advantage of this line is that it lets you throw bricks into the mid--it's always nice to have a place to get rid of useless cards without hurting your chance to make FL. The disadvatage is that you're pretty much limited to making some combination of 4s and/or 2s (2-pair, trips, boat) or a baby straight, but if you catch only one of those cards on the first draw, it can close the door on the other options.
My set lets you adapt to what the first draw brings. Say you get a lucky first draw like T:s:9:s:3:d:. Putting the T:s:9:s: in the bottom leaves you open for the 2-pair/trips/boat line, or a straight draw, or a flush draw. But even if you draw something like Q:h:8:s:7:d:. you can put the Q on top, play the 8:s: low and have a lot of flexibiltiy for the second draw.
