Brando... I know my speaker pods arent as contoured as yours were, and arent perfectly acoustically positioned, but they work awesome, I never kick them and they havent expired from water getting into the doors!
Why not make something in your door? Its dead easy, and there wont be any metal cutting involved, there are already holes cut in our door panels for such a thing.
As for the tweeters... Dont know! You wouldnt be able to remove the factory front speaker covers in the dash, and build a fibreglass "tube" that positioned your tweeter where you want it? I would think that would be the best place for them, if you can make it look 1/2 decent... I'm sure you've already pondered that idea though...
