One question about the HHKB ANSI plate:
- is it possible to setup the bottom row like that: 1.5 - 1 - 1.5 - 7 - 1.5 - 1 - 1.5 ?
Yes, that is exactly how the plate is set up. If you want to have the HHKB bottom row, you simply don't install switches in the outside 1.5 positions.
JDC ... Isn't the HHKB a 6.25 spacebar?
It's 6 in size not 6.25, no?
It goes from 0.75 on the X to 0.75 on the ,< key.
Something like this would give the board true HHKB layout while giving the opportunity to add three more keys.

Actually, that layout is supported by the PCB. The 6x spacebar center mount is offset, and matches with the 7x spacebar center mount position. I'm not sure about stabilizer holes, though. It would be up to the plate and case designer (aka WFD) to decide if he wants to change the case and plate design to the "true" HHKB layout, or stick with the 7x spacebar design as it currently stands.
Sorry, but I don't think we will be adding any more layout options at this late date. The 7x spacebar seems more appealing anyhow, as they are more commonly found (e.g. in tsangan kits), and it fixes a problem with the HHKB, by creating a balanced symmetry on the bottom row. PFU Fujitsu doesn't have to worry about spacebar compatibility, since you don't have many options for replacing the keycaps, anyway.
Also, by using the 7x spacebar in that configuration, instead of a 6x, it matches the 1.5x (and WKL) layout.
