Makes sense in theory, but probably not easy in practice, unless the company is relatively large. If the company is just one luthier, or a handful of luthiers, who do almost everything by hand, the prices of their instruments will be boutique. To offer a cheaper range they'll need to decide to have the components shipped in from, say, the Far East, get a dedicated person to assemble them in their workshop, do the QA and sell them at a lower price. That leads to a different business model, so it has to be a conscious, calculated decision not every luthier is happy to take.
Edit: and perhaps then they'll start having even cheaper models built from scratch in the Far East, etc. That shifts the focus from low-volume, hand-made to a larger, more mass-produced business, and will need a restructuring and the influx of exclusively business-minded people into the company.
