Baby girl middle name help

Hello all!
I'm having a baby girl expected May 26th and am having a hard time choosing a middle name for her. I originally like Myla Alanna Thomson but majority of people including myself feel like the double A's shouldn't mix although I really love both names. Anyone have any ideas for middle names? 
I love Hawaiian names and names that have strong meaning. Myla means merciful/soldier from what I read. Alanna means beautiful/peaceful which would give be peaceful soldier or something along the lines of that. 
All ideas are much appreciated!! 😊😊
