A serious big thank to the OP.
That's exactly what I was looking for! (beside the Note2, I have an S4 LTE A E330s running stock 4.4.2 ROM with the same keyboard as the note 3, and was sad to use the old keyboard on my Note2 running 4.3)
I can confirm it works perfectly with ARHD 20.1.
As it was said; the only diference with the Note3 keyboard is that emoji are not in colour.
