I can see where you're aiming at in terms of aesthetics "cleanliness" by keeping the function keys on the right side of the board vertically upright. It can also maintain a balanced look as long as it has vertically aligned light indicators on the left side (num/scrl/caps light).
I'd say we need not to worry much about how Maja may "look" similar to other boards, because it's not. It is quite unique from the get go by the fact it seamlessly incorporates the nav keys into the ergo layout.
Having even spacing blocker by adding one more 1U (or 1.25U) on right bottom row adds that venerable WKL elegance to it.
It's quite tempting to add additional function keys or macro keys to the left side, but I'd say that we should restrain from it as it will ruin the whole ergo aesthetics in its simplest form yet also complete. It may also add additional cost to the production.
I hope Maja could be the best ergo board that assimilates best ideas from Alice, WKL, TKL and HHKB, and yet still unique in its own way.
Lastly, for the sake of Majapahit spirit
.... please refrain from using the modified Majapahit logo that looks like Shuriken
Having a simple pvd brass octagonal star Majapahit logo on the back is more classy (think Fusion60, Singa, Polaris).
Cheers!
