Thinking about it, a Duke Nukem game set in the Indiana Jones world could be great! Duke goes back in time to 1930 (give or take a few years) and has to stop the Nazis from finding the magical something-or-other, because it has the power to instantly kill millions of people at will, so if Duke fails then the world will be ruled by the Nazis, who will kill off everyone else. Part way through the game, the Nazis will start to attack Duke with alien weapons as the Nazis have found a crashed alien space-craft, and so they've manged to duplicate the alien weapons, and Duke will have to find the space-craft and destroy it before the Nazis fix it and make it fly (as otherwise the Nazis will use the space-craft to destroy ever major non-Nazi controlled city in the world). And maybe the crashed ship has lots of pig/lizard/etc alien clones, who would fight alongside the Nazis against Duke, because the SS officers are mind-controlling them.
And at the game's end, after you finally find the magical thing, and destroy it to stop it falling into the Nazi's hands, you have to fight Hitler, who is equipped with the best weapons and augmentations that were found on the space-craft.
The Indiana Jones style humour could work well in a DN game, I think, especially when mixed with Duke's over-confidence and tactless remarks. He'd be disgusted that 1930's American women wear so many clothes, and that the music/movies/vehicles of the 1930s are (to him) so lame, and he'd be upset and angry that prohibition meant that it was hard to find any alcohol to drink, and so he'd complain (comically) about all these things as he went through the game.
