With at&t the only way to have custom recovery with kit Kat is to go down to 10d(First version of 4.2.2 on it) root and then install Gary's modified kit Kat which is a mix and match of 10d and 20c which will be the same thing that will be with other models just have to wait for a)kernel source(each model has a different kernel so they have to be built with the specific kernel for it) and b)for someone to build the Rom(yes many can do it but it's better if they phone model to test on)
Edit:here is thread for you to get it in d801
