Could be done, but reasonably, no.
I would assume you need to change all 3 gearboxes to not upset the computer, as I'm not certain changing the diameter of the front tire size to compensate for the rear changes would interfere with traction control. Then you have the issue of having gears made that will work, you're not going to find something to just swap in there. You're probably looking at $10k-$15k just to test it out, and hopefully nothing breaks in the process.
Or you could just wait a bit because the plaid is on its 3rd year now and will probably be getting some minor performance upgrades within the next year or two...Unlikely that we would get an OTA power bump as well, but that's also a possibility.
