I would have liked to see a courthouse acid-toss on Dent by Boss Moxon (or really, whomever). Either way the event still turns the DA's sensibilities on edge, but as long as they were already IN a big trial, using the original Two-Face creation would have been easily accomplished.
Of course, they called him "Harvey Kent" in his first few appearances before deciding to change that to avoid confusion with a certain "Clark" with the same last name.
