Here`s the original staggered layout.

Usind the Q as reference, we have the following on Planck:
- The A moving 0.25u to the left.
- The Z moving 0.75u to the left.
Planck

Now, with my suggestion:
- The A moving 0.25u to left.
- The Z moving 0.25u to the right.
Modified Planck

Besides, we must consider the proximity of the letters to the home keys, which is better with the mod.
What could be placed under the A is another matter. I just think this is more intuitive.
What do you think?
