There are more Mod's for the Hemi than V-6, but there are some.
Tire pressure to MAX rated psi.
Change the T-stat to 180. Adjust Temps in ECM.
DIABLO Sport has a Tuner that contains a Eco Tune, may even be a Tuner guy that will build a specific tune for the V-6.
Lower does work, or at least extend the from dam 2+".
Just some idea's.

I've run 44psi before in my truck and it ends up making the speedo off by 10%, but I have the 33" tires.
I'm aiming for at least 25mpg; time will tell.
Superchips may have a tune for 2014s; can't recall. My Superchips tuner has an economy tune, but I get better results using the towing tune...in town anyway.
Since I also have a RAM, albeit it older, I suggest a warm air intake. I currently pull air through the radiator, right next to where the upper radiator hose enters. I can get a 30* temp rise almost all the time with my current setup. With an engine computer that uses manifold air pressure (MAP), and not mass airflow (MAF), this trick works to increase mileage. I get about 5% more mpg. 5% of 20mpg is 1mpg...
Centerline wheels are 20# each for 17", but they're not really worth the money just for saving on fuel. You might be able to find some OEM TRX wheels; they are 23# each.
I've not lowered my truck, but I did put drop shackles in the rear end to level the truck.
If you don't tow or haul much, you could remove the overload leaf springs to save some weight. Same for the spare tire.
