Feasible but not likely
The plans for a -6 (and -3, -4) enable construction from raw materials and include for example details of form blocks to fabricate ribs, bulk heads etc. and components for weldments.
But it would take a tremendous amount of extra work to turn raw materials into: wing spars, gear legs, canopy, engine mount, cowling etc. and would require heavier equipment and more expertise than is common.
