If you want to use a single sided caliper with larger brakes you can grab more common off the shelf rotors like the 2007 Charger RT.
You will need to turn your rotors into hubs and install slightly longer studs.

The Charger center register and bolt pattern are the same as your truck. The shallow offset of the rotor means a floating caliper will be required. You will need to adapt the siding caliper mount to the spindle.
It's possible to do that but, again, I'd need the spindle, caliper, hub, and rotor to build it.

That would give you $30 rotors (13.5") and $20 pads. All parts would be off the shelf except for the hubs you make out of your stock rotors.

17" wheels would be required, possibly 18" depending on the caliper chosen.
