Yes, all this makes sense. I assume that any continuation towards Colne is along the line of the Crosshills/Glusburn bypass last discussed in the ninetiesTake it roughly parallel to the Eastburn Beck then to a grade segregated junction on the A629, and include a link to the back of the hospital too.
Regarding Cononley, is the logical route for any replacement up and over the cricket pitch and station. I appreciate the height differences in the land and huge outrage.
