Damn, I didn't think about weapons. That might be hard to balance. I think what I'll do is set the time period to be in Jones' era, so the smugglers can have a tommy gun-like weapons. I'll see what I can dig up, and I will try to vary the weapons based on team.
I think what you need really is just the two teams to have different weapons, but they have identical roles and stats.
So, one side might have a tommy gun, yet the other has a differing sort of machine gun.
The games get unbalanced when one side has, say, a rocket launcher available to them, and the other team has a sniper rifle.
It might be cool that they have different weapons, but one team can't get long-range kills and the other can't kill lots of people in one go.
Having a set-menu of weapons, like a pistol, a machine gun, a grenade and a rifle works fine.
Then both can have alternate versions of the same type of weapon. You just make sure that all mahine guns have the same damage and fire-speed as each other.
Smugglers works well as a title.
If you want to make it sound less like a generic term, then just try "Paleontologists vs Dino Smugglers".
