AoE is Katon, not Hyoton. Otherwise, this is pretty much the same method I use, simply because I have those set up in that order on my controller. Left to Right are Raiton and Suiton. Reverse the order for Katon and Huton. Doton just ends with the middle Mudra. That just leaves Hyoton under Kassatsu, which just shifts over one button from Raiton. It's a lot of words and sounds confusing, but actually playing it feels natural.
