if you read my first line I want to expand all dimensions in proportion stopping when the headroom reached 6 feet,
nowhere did I say that I wanted to keep the 20' loa.
As to the headroom requirement,having lived in a sailboat 4" shy of full headroom for 6 years fulltime caused back problems.

Well, you change the headroom to 6 feet, but it then would be a much
different boat, with perhaps unforeseen repercussions. (For instance,
with the higher cabin, could you still have vision lines looking
forward from the cockpit while sailing?)
If you need a 'full size liveaboard' 6ft headrom in a 20 foot overall
length, that gets into the 'pushing the envelope' realm. Not that it
isn't inconceivable. The PB&F designs 'Col. HG Hassler', and
Superbrick both do this already. And, believe it or not, the 15'4"
Micro Navigator has about two square feet of standing space tall
enough that my 6ft-0in body can stand up straight enough to pull up my
pants with the cabin hatch closed.
Another way to achieve this standing headroom desire is to use a
tent/awning above the slot top cabin. I don't see any problem with
rigging a simple tarp strung on a rope stretched between the main mast
and mizzen mast of this Chebacco RD to give full length walking
headroom from stem to stern with this design as is.
And, plenty of 'old salts' have argued persuasively that standing
headroom in a boat is much over rated. In all honesty, +99% of the
time while a boat is being used you are voluntarily by choice either
seated or lying down. For the other 1% of the time, the cost of the
necessary compromises is questionable value.
