Again I guess it doesn’t matter being a harp
One might play it as a harp, sure. One might play it simply by tapping upon the strings/frets which supply the required note. It's a common guitar technique and has been adopted by bassists too. It really depends on what timbre you want to evoke, because different styles of attack yield different sonic results.
The neck itself could be one board, or several long pieces glued laterally. The latter would probably be better in construction so long as the grain of the pieces of wood are arranged to counteract the torque imparted by such a broad disparity of tensions across such a wide range of strings.
In other words, some strips cross-grain, some length-wise, some with back-bow, all supported by truss-rods, in order to keep such a wide, thin piece of wood from twisting.
My #1 guitar right now has a three-piece neck. The pieces run length-wise along the neck. The two outer pieces run the grain parallel to the string in order to prevent the neck bowing (binding to the front of the guitar, towards the strings). The center strip is cut and glued cross-grain in order to prevent the neck from twisting out of true.
I doubt one-piece construction, even with truss-rods, would support the combined tension of all those strings without moving around. Even if it dd, it would be a maintenance nightmare.
