What I actually disliked in the Moonraker idea was the low gravity, Then it just makes it an LTK match with lasers only. Sure, It would fit the theme to have low gravity with lasers, But I wouldn't like to play that, Really. I played in a public WNx party night with low gravity (And I mean really low.) and seriously, It was hard to hit someone flying all around air-strafing and all.
However, That is just my opinion.
EDIT : Re-reading the whole original post again, Goldfinger could be quite a challenging one. Although in small maps such as Bunker, Library and Basement, I wonder how could we fit 60 goldbars in there, Unless we stack them by 3 or 5.
