Well theoretically they have already designed it all, so it would be cheaper to make.
That's like saying it would be cheaper for Honda to re-establish a line to build their 1975 Civic on the older, less efficient, less automated line. Sorry, but no, it would be horrendously more expensive.
Canon has said before that when they design each new model, making assembly techniques more efficient is a major goal of introducing a new model in the first place. They introduce new models not just to sell more features, but also to lower costs with constantly improved assembly techniques.
The new 60D, for instance, may be underwhelming in terms of new features, but it's a sure bet that it's substantially cheaper to build.
Going backwards in time to a design with less efficient assembly design would not be cheaper, it would be more expensive.
