I don't think you can have more layers than you do aura. You can probably make a single area exceptionally strong and minimize damage felt with practice, but other areas would be vulnerable, since the aura that is there normally. Its equivalent exchange: if you want one thing, you have to give up another. You can't have a fully tank like aura barrier on a whim, probably only after years of strengthening it.
