Can you saw the boards, like cutting thick veneer off the two faces? Just read 
a bit where that was done with a tall clock door panel to preserve the original 
veneered front and back finish. The thin slabs were then pressed flat and glued 
to a new core that had been well dried and planed flat.
There's a job for 3D probing and milling. Probe to get the shape of the two 
faces. Bandsaw as best as possible to split the warped boards then with the 
finished sides down, 3D mill the sawn sides to make an even thickness yet still 
warped board.
Make cores of high grade plywood and fill the gaps around the edges with wood 
that matches the faces.
Which is how I might have done a lid to keep it from warping or splitting or 
cupping. Not the old way of doing fine woodcraft, but neither is CNC machining. 
;)

What are you looking to do is this veneer or architectural size?  In either 
case you end up using many thin sections with slow setting glue bent around a 
form and clamped. Sometimes steam is used
