Something I've learned, working with concept artists, is that if you find yourself having to explain your idea over and over, there's a problem with the idea.
There's a reason The Maltese Falcon doesn't have battles atop German Zepplins, and Indiana Jones does not descend into a world of moral ambiguity. Some genre's mix well, some don't. Sometimes it takes a singular work of genius to mix two genres and everything else ends up being a ripoff of that one moment where someone caught lightning in a bottle.
The idea that your own personal campaign does both is great, but as a brand I think there's a problem. If you say "pulp-noir" it creates a certain expectation. If you have to correct them, then you probably have the wrong brand statement. Just call it pulp, and let the noir speak for itself in the urban supplements.
