This is one of those things they didn't really anticipate or account for, so the answer is indeterminate, unless you write a letter to FAA legal and get a written interpretation. My best guess is that if pressed, the FAA would specify that the obvious *intent* was that you complete the entire 141 training program, including the EOC checkride.
I don't think you could take a ride for a rating you already posses, but you can certainly have the FAA remove the IR from your ticket and do it all over again. Plenty of folks have had the 737 type removed from their ticket, you just submit a written request.
As JB said, it would be a waste of time and money.
