From your description it looks as if you don't actually need to inherit
from KoCreatePathTool. That can be implemented directly.

    <p>
      My idea is to have points/anchors/nodes but not bezier curves, the
      selection would just be a vector of points like what the outline
      tool does and the points/anchors/nodes act as checkpoints where
      you can go back if you make any mistake. Though some of the
      functionality of the path tool like creating points/nodes/anchors
      on click, removing points/nodes/anchors with right click and
      completing the path when the user clicks on the first node will be
      duplicated. Is that enough functionality I am borrowing that I
      will redoing the Path Tool, though feels like the polygon tool is
      a closer candidate but I am confused. :-(<br>
