I have a couple ideas when it comes to ability names. I recently did a go-over of the Punch Art/Martial Arts abilities some of these are referring to, since FF has a history of reusing terms this is all quite interesting. Take or leave these however, I don't care.
-Spin Fist can be Spinning Fist and Pummel can be Pummeling Fist (or Repeating Fist, but that's kinda meh in comparison). These are both in the same tree so you could say they go together this way.
-Secret Fist came from Secret Hole Fist. This may or may not refer to punching the Death point in qigong internal healing also known as dim mak, or Death Touch as it’s referred to in the west. This could fall in line with Chakra, but also talks of one single blow. Fist of the North Star actually translated this as the Hidden Points thing (but that's probably better for a whole FotNS tree or class, not making any suggestions.)
-Later on, Earth Render became Shockwave or Rockbreaker. But that was (mostly) not to Monk/White Monk. Works better this way anyway in cooperation with Air Render.
-Aura Blast and Far Fist come from the same term
, which is also where Wave Fist came from. No need to change these but it's a funny little tidbit.
