would be funny to make a map projection that made the great circle a straight line.
I don't think that's possible in general.
Gnomonic projection, as mentioned in a different comment.
Gnomonic projection can only accommodate ½ of a sphere even on a map extending infinitely in all directions. It's not possible to map a sphere onto a plane, preserving all geodesics as straight lines.
thx for correction
Does not project the entire earth.
You can't do this for all great circles, because sphere geometry is incompatible with plane geometry. Great circles all intersect each other twice, but straight lines intersect at most once on the plane.
