My point is NOT that Mr Lucy is the best choice for BOND but that a younger Bond (of his ilk) is a necessary gamble at this point.

Going with a young Bond or a rebooting of the series is not a necessary gamble. It would be a foolish gamble that could ultimately lead to the end of the series. There are several reasons why this would be:
1. The MAJORITY of fans don't want to see Bond, a man who has always been described as someone in his 30s or 40s and has always been portrayed that way on the screen, as some little child in his early 20s. It's completely unrealistic for someone like the Bond we're used to seeing being portrayed by someone who is barely of legal age to drink, who is barely of legal age to enter a casino, and couldn't possibly have had much experience with the ladies, which a Bond in his early 20s wouldn't have.
2. It would be box office suicide to go this route. Despite what some of you may think, even people who aren't that fond of the James Bond films still have some idea of what the character should be, and a lot of them still hold the integrity of the original character in mind when asked about who should be the next Bond. I know someone who absolutely loathes the Bond movies, but somehow the conversation came up about who would be the next Bond when I was talking to that person, and that person didn't like the idea of a young Bond, and said that it had to be someone in their mid 30s or their 40s, and Clive Owen was that person's pick for the role, despite that person's hatred of the film series. So, I think that if there are people out there who don't even like the films who care somewhat about who is cast, then going with someone totally unfit for the role, like someone in their early to mid 20s, would not go over well with the majority of Bond fans or the general moviegoing audience.
3. Also, when was the last time any of us saw a franchise get rebooted and actually have success? The
Star Wars prequels, while they have made tons of money, have been awful (I haven't seen III yet, but the other two were downright terrible), so it could be said that those films were failures as a way to "reboot" the series.
I think that whether or not Wilson and Brocolli go through with this reboot nonsense will depend on how well
Batman Begins does critically and financially. If it is a bomb, or if receives downright awful reviews across the board, then I think the idea of a reboot will be shelved, because if it can't work with Batman, then it won't work the Bond series.
