It might make sense that before implementing an entire laptop from scratch, a kit could be created to replace the normal motherboard with this "upgraded" motherboard.
Basically, choose a laptop that can be easily found, like a ThinkPad or Inspiron, etc.; it can be a generation or two old to save cost.
Create the motherboard to use the existing laptop and use the existing battery and display.
Sell the motherboard as kit and also convert a few laptops for a turnkey solution.
Not ideal but this simplifies the process greatly.
