Have a strong female be another 00 agent and be involved a bit more in the movie, but keep 007 as it has always been. Simple.
Also, just to throw another name in that I think would be a fantastic Bond:
Richard Madden.
Just saw this story about an awesome corn maze with a Bond design(See below), and got me thinking again about who the next Bond will be. Never really a fan of Daniel Craig tbh, and hard to beat Connery or Moore, but my personal choices are either Tom Hardy or Tom Hiddleston. Any other Bond fans...
