The narrowing of the two bottom keyboard rows on the Gemini and Cosmo came directly from the design of the Psion Series 5. Maybe keeping the sides of the Astro keyboard straight, works better with the slider, or, perhaps, they had to nudge things around, to make room for the fairly deep main camera module? They hinted at something to that effect in Astro Update #10. I wish Planet would be more vocal about such details.
Anyway, in all the Astro images and videos thus far, all rows of the keyboard has been of equal width, though, previously, the extra width of the two lower rows was added to the outermost keys on both sides. While I'm not into key swapping either, I do remember seeing someone putting all the arrow keys on the bottom row, allowing comma and period to sit to the right of M. That particular mod would have been possible, had the extra width been given to the outermost keys on both sides.
I'm a bit surprised to read that æ, ø and å wouldn't work with Caps Lock. At least on my Swedish Cosmo keyboard, Caps Lock works with the Swedish å, ä and ö.
