One downside to your theory is you are leaving your reputation for building the highest quality replicas vunerable to downgrading because of poor build quality by some amature builder . You no longer have quality control. Someone does a poor or unsafe build that other knowledgable car people see and the builder says " oh yeah, it's a Kirkham" . That may scare a potential buyer, so yes, you sold a lower price unit, but you just lost another potential customer. Just playing Devil's advocate.
Personally, making your cars "more affordable" decraeses the value of mine, which was bought as a "rebuilder", but the price I paid was determined from the new complete car price at the time.
I know, these cars are not for investment purposes, but I'll bet your other previous customers would hate to see their cars value decrease. I know it's sort of comparing apples to oranges, but a lot of people don't look at it that way. They will think " why should I pay 60-100k for this complete turn-key used Kirkham, when I can buy this basic kit for (insert price). Even if they can foresee every additional expense for parts, they will not include their time (labor) and their final tally will make the factory completed or pre-owned car look like it's overpriced. That will affect used existing car prices.
