Here is one that puts backspace at the East action button, which is actually a pretty good spot for a backspace key. Home and End are the new action buttons in this arrangement, and you get a dedicated Del key but not a dedicated Ins key (which makes sense because Del is probably used much more frequently).
I labeled the P+1, L+2 keys in a way that is inspired by the
Swiss keyboard layout and which would work fine for German, French and Scandinavian languages.
The M+3 keys are completely standard US-QWERTY.

Actually I never thought I would like a layout without a dedicated number row, but this one I could live with. All punctuation symbols are on completely standard primary/shifted keys.
One potential problem though: people who don't use the shoulder buttons will have a hard time with the Shift+Meta symbols on the left: !@#$%. It can be done though, if Shift+Meta is a sticky Shift+Meta.
Interesting - I like it with exception of the game pad buttons. The 4 button set needs to be like on the Pandora:
Home: To the left of page.
End: To the right of page.
PageUp: To the top of page.
PageDn: To the bottom of page.
Frankly, THAT set should NOT be broken. Particularly by inputting Delete and Backspace into it. Insert and Delete work on the two additional buttons, but we have to find somewhere else to put Backspace.
Hmm...
So, working off of the _wb_ modification...
I'm assuming FnMetaGeorge+Enter = Compose. Why? It's a _wb_ layout.

Important changes:
Insert and Delete are returned to where they make better sense - 4 button game button is again PgUp, PgDn, Home, End.
Backspace has been migrated to the rafters. Not sure I like it there either - but frankly its much better than having it in the game pad keys.
PrtSc is top layer again. Alt+PrtSc is a common action and shouldn't require a Vulcan death grip to do.
Pause is top layer again. Ctrl+Pause/Break is a common action and shouldn't require a Vulcan death grip to do.
Esc is on the Fn layer. It won't get hit by accident, but is easy to hit with Fn+ key.
Alternatively, I'm still thinking that Backspace = anti-space = Fn+space is an interesting concept.
This solves a serious problem with this series of layouts, BUT it has a rather interesting drawback to overcome. I think we could get used to it.

Before anyone gets upset with this idea, give some consideration to the gains.
Insert and Delete are sometimes used with modifiers Ctrl+Insert, Shift+Insert are real things.
I'm unaware of ANY use cases when Backspace is used with a modifier.
Backspace on Fn+Space makes as much or more sense than having Tab on space (Pandora).
Thoughts?
