what do you think of remove the 5 column to remove lateral movement of the index finger (t,g,b) and instead use combos like (e+r = t, d+f=g, c+v=b)?

Let’s say I don’t mind slowing down my typing a bit, but I’d rather strain my fingers less.

For now, I’m using the Miryoku 3x5 layout, which has already reduced the lateral load on my pinky finger. Now, I’d like to remove the lateral load from my index finger as well, leaving a 3x4 layout.

Has anyone done something similar?

Thanks!
