If that's the design philosophy, limit the power output to 60 W PEP.

Elecraft already have *two* other 12V capable radios - the KX2 and KX3 -
of one doesn't count the K2.  *WHY* create another dirty 12V radio
("active predistortion" is not the solution) when one can have a clean
60W radio at 12V or a clean 200W radio at 40V?

Build a DC-DC supply for the 40V PA stage if one wants to run it from
an automobile electrical system (or install a separate 48V alternator,
regulator and battery specifically for the PA stage).

Increasing transmit IMD by a factor of 40 just to operate the radio
at 100 W PEP on a 12 battery is unconscionable given today's state
of the art.  It was different when 48V transistors/FETs were not
available but that ship sailed almost 20 years ago.
