So, I think the problem a bit for you, and the industry at large really, is that the current buying power engine for these lines are the people who grew up with the JGL style guide as the template and thats what drives the nostalgic urge to collect these things. The number of people who read the books in the Silver and Bronze age DWARFS the number of people reading modern books - that is coupled with the fact that the people with the most disposable income currently inclined to buy these action figures have the nostalgia for those looks. So while you feel they have been 'done to death' I promise you sales numbers will bear out that they sell through better than figures based on the most recent comics.
