Historically, I don't think it has worked like this for Intel. It costs way more to have multiple designs so they are all pretty much the same few chips with the packaging changed to disable parts. Sometimes the disabled parts failed QC but the numbers that fail QC but are still usable are not high enough for the high volume parts. Really it is just a way to do differential pricing. Some people will pay $500, some only $100 while the part only cost $25 to make. The way to maximize profits it sell to both, and find a way to justify the price difference.
