One way to do that is to add thicker and transparent 3D lines (as you have suggested).
But a better way is to convert line's 3D positions into 2D screen positions and then get the closest line from mouse position in 2D space.
A sample on how to do that can be found with the samples that come with Ab3d.PowerToys library - see "3D lines" - "3D line selection" sample.
