I decided to pixel parts of my collection and ended up doing some templates which might be of use.
1. The HHKB I found here was missing an R4 key. Adapted logo and bottom row by one pixel as well.

//before, from OP: (I guess the errors are deliberate to get a bigger logo?)

4. 1px wider PokerX for nicer bottom row gaps.
