I need help finding a starting-place model of a split keyboard

Below is a Cirque Wave Keyboard, which is no longer manufactured by anybody. 

For years I have wanted to model this keyboard so I can move the touchpad to a better location (for me).  Then I could get the chassis models made by [blanking on the name], add new PCBs and keycaps, and finally have the keyboard I have always wanted.  I'm okay with every aspect of this, but I've been unable to find a base model to start from. 

I have been unable to find such a model over the years, and I don't have \\\$1,000 to pay for 3D scanning.

Can anybody point me in the right direction?
