I'll strongly suggest changing the approach from character input to phonetic input like the stenotype machines. Creating a nice set of rules prioritising writing speed is of course no easy task, however I think it is the only viable way in my opinion to make it usable.

And with a software assist, it should not be that hard to convert the phonetic input to "standard" text
