GURPS Supers Campaign, could use feedback.

So I've been tossing around a GURPS Atomic Horror/Supers/Space kind of game, the sort of thing where the players make 100-pointers in GURPS Lite to start out then add 350 points in advantages and such after a session or two.

Set in 1950, flying saucers, shooting for a classic appearance, using some updated versions of the species from GURPS Aliens.

I'm tempted to use yet another classic (Nazis on the Moon) as a sort of tutorial once the PCs get their super-abilities, but.. is that too cliched?
