Again, the first issue to overcome is rights to the products. Champions/Hero has gone through multiple hands over the years. And, as a consumer, I have no idea what those original contracts included as far as rights. Or if/how those rights transferred as the IP was sold. Even some (all?) of the original (playtester) characters are owned by the original players, and would need to be licensed separately.
This is not likely to be a money-making proposition. So, while I don't speak for DOJ, I'm pretty certain this won't happen as a company project. I can't imagine they would object if you wanted to take on the task yourself though.
