Perhaps more useful would have been the abandonment of Stirling and Wellington production much sooner and turning the capacity over to Lancasters.
This book:
Lancaster: The Second World War's Greatest Bomber: Amazon.co.uk: Leo McKinstry: Books Recounts Harris' continued efforts to see the end of Stirling and Halifax production and retool for Lancasters. But, it seems, HP and Shorts insisted on being allowed to continue to manufacture their own designs.
Harris was quite scathing with regard to even the Halifax as he felt that his needs would be better served with a whole Lancaster force. Even in wartime he seems to have come up against vested, comercial interests.
