Much as how Rachel Dawes was used and not Harvey Dent in Batman Begins, Holly wouldn't have been represented correctly with the way the character was used in TDKR, so giving her a different identity of Jen is the best way to go.
If they wanted to go for Holly Robinson, one would expect her to have a worthwhile storyline in which 'Jen' did not.
