Basically SE has confirmed that interracial things can happen, so clans would as well. However, I don't think coming up with a term to encourage it is a good idea. It's supposed to be pretty darn rare as is due to cultural differences between the races, the same holds true for the clans.
While we'll have to option to mix clan traits more than we did in 1.0 in ARR, again, it's something that's supposed to be uncommon.
