You know, it's interesting. I initially thought from the title this would be a 3.5 thread, but there was no good reason to think that. Now having read the thread, I'm struck by the lack of options in 4e. In the 3.5 thread I was imagining, someone would be asking for some tweaks that would help the character pop out more as an individual. Instead, in this 4e thread, the focus is on mechanically differentiating the character.
So my suggestion is actually to "spice up" the character by coming up with approaches to playing the character that are appealing. To be interesting, a character should have goals, mannerisms, limitations, etc. It may not matter as much if you are stuck being a MM spammer if you intersperse banter with the other characters or challenge enemies to do their worst. Gandalf got a lot of mileage out of a simple Magic Circle Against Evil... "You shall not pass!"
I think together with the game mechanical advice already given, you can do a lot for this half-elf.
