If you don't load any Awakened abilities you can go for full Duelist and and full Kung Fu with the exception of the Grandmaster ability, or vice versa, full Kung Fu GM without the Duelist ability. Don't load any abilities that cause the same effect, like 2 moves that both cause powerless or such, and it's possible to have space left for Awakened abilities.
The level 50 abilities take up 5 spaces of your memory, which is quite a lot. The 5 tactics both abilities grand ain't everything so it might be wise to not load them and have room left for other abilities.
But why don't you load SMG and Kung Fu, or Aikido and Duelist? Considering that some SMG and Kung Fu moves need the opponent to be dazed. As does Aikido and Duelist, both have some moves that require the state off-balanced.
It's possible to mix them and have loads of moves in each tree. Try varieties of loadouts in game with different moves, with or without Awakened abilities, to see what works best for you.
