i think it would be a longshot to bring back the plymouth name, but i don't think it is out of the realm of possibility to see some of thier car names back.....
And if the "Challenger" is built like they say it will, I would bet within a few months they will announce a "limited edition - Challenger w/ a "Cuda" package". If Chrysler is willing to put the name "Charger" on a four door w/ a six cylinder, then they will use any name they think will sell. To get a Hemi you have to get the "R/T" version, but R/T doesn't mean Road & track. That's another option you have to buy.
