A pure airfoil can be cd .07. A snow cone can be .16. Which is still way better than the .60 cd you are starting with
The total drag of the streamliner with a straight tail won't be twice as high as the vanishing value of an ideal airfoil because you will never achieve the drag number of the ideal with mirrors, heads and hands, egress gap/ side wind vent, lights, ect, sticking out anyway. Keep it simple and get it built or you will end up like so many grand designs I have seen presented here with it half way done and never finished.
