Cost is kind of irrelevant to the customer, they only care about the price. Spending so much in R&D that you can't sell the product at a profit is a classic mistake.

We'll just have to see if people are willing to pay double for the Chapmans what the B1's would cost them.

I suppose MP could make the situation better by releasing a low deck Megablock. Then the Chapmans are kind of cool since you can run the RB manifolds and make a ton of power. Putting the high port heads on top of a RB block always seemed a little clunky to me.
