As mentionned elsewhere, half-breeds are too often a way to say "hi I'm special" and generally frowned upon if it's mentionned often. Someone who comes up and starts RPing by OOCly describing their half-breed-ness or mentioning it ICly will likely set off a dozen of alarms in other RPErs. 
The impossibility to portray it in-game has been mentionned...
As far a half-duskwight specifically, I believe duskwight are possibly the most insular species so a half-duskwight is possibly more rare than any other half-breed.
All in all, it's your choice in the end, but it's risky.
Anyways, if you want to play with racial profiling, playing a duskwight might be enough! There's a thread about Duskwight somewhere around here...
