I can only agree with you on Toon Link. All your other reasons are based off of opinion, even Toon Link to an extent. Also MegaMan is not a dead franchise at all. Just because there hasn't been a game doesn't mean he's dead. In fact, his franchise is one of the largest in gaming history. Plus he has comics and tv shows among other media. By that logic, you would want to cut Captain Falcon, the StarFox characters, and ice climbers just to name a few. Also, if you were developing the game to make the public happy, you should probably include better variety so more people would by, rather than strictly doing what you, and only you want.
