The easiest way to do this would be a complete engine conversion to an engine/transmission and ECU combination that doesn't use DBW.
If you have a manual transmission, it may be technically possible to do the physical modifications for a cable-actuated throttle, then use an aftermarket ECU (like MegaSquirt) to control the engine. But that would be a massive project to get the custom ECU configured correctly. You'll also have tons of fun trying to figure to how to integrate it with the stock electronics system so that the dashboard, etc, all still works. In this aspect, it would be similar to an LS V8 conversion.
If you have an automatic transmission, it's probably nearly impossible.
The stock powertrain control system is "torque-based". The position of the pedal is not simply converted electronically to a throttle blade position. It is interpreted as a desired amount of acceleration or torque at the axle, taking into consideration the current speed and likely other things. Then a crap-ton of calculations are done to finally decide what the throttle position, ignition timing, fuel ratio, etc., all need to be to produce the desired amount of acceleration. All those calculations depend on various properly-calibrated lookup tables so the computer can make accurate assumptions about how much torque the engine is producing right now, and what combination of throttle/fuel/spark/variable-valve-timing would produce the desired amount of torque.
During these calculations, multiple sub-systems (traction control, speed limiter, rev limiter, torque management for auto transmission shifting behavior, etc) all have the opportunity to "deny" the torque requested by the driver, and limit it in multiple ways. This all involves another metric crap ton of lookup tables that must be properly calibrated.
With the auto transmission, the transmission controller is integrated into this system also in terms of desired output torque at the axle and current road speed to decide what transmission gear is best right now.
So, no... you can't just slap a cable-actuated throttle body on the engine and expect anything to work.
This is what makes it so difficult for forced induction kit manufacturers to create custom tunes. Plus, Chrysler doesn't openly share details of how the system works, what lookup tables are involved, how the lookup tables affect things, etc.
Here's an intro to how a torque-based ECU works (specifically for the Dodge Viper, but generally relevant in concept for any torque-based DBY engine system):
