Is there a keyboard like the Piantor Pro, but with a better thumb-key layout? - eviltoast

Something like this? The heavy stagger is great, 42 keys is almost perfect, but the thumb placement is – for me – horrible. Having to move my thumb to practically under my palm is just terrible ergonomics.

This thumb layout reminds me more of the ErgoDox variants, and is far better placement. Is there a layout close to this?
