*snickers* Yes, he needs more love, but wow, he's getting it. I just hoke Kishimoto will do more with him ;_;
I don't mind Hyuugacest, because their culture is probably different on that, and d00d, even if the twins thing was considered a bit too close for comfort, Neji's genes are good enough that they might wish to bring them back in the main house. 'sides after so long with a bloodline limit, i'm pretty sure they must have bred out a lot of gene defects. Most Hyuugas would probably see it as branch-marrying-into-main first; the separation of the two sides is so harsh.
Anyway, nothing says Hyuugacest has to happen, since it hasn't been stated in canon yet, but it's damn easy to justify XD
You can't 'breed out' defects caused from incest though. Breeding 'in' is the problem. I think that while bringing the branch back to the main is a good idea, the chance of having physically and mentally retarded children would be a greater disgrace.
Actually, you can. Each generation, you'll get some viable children and other - for a while, rather more - damaged ones.
Most of your viable children will be carriers of the same recessive genes whose active forms caused their siblings' defects.
Others, a few, won't. If you can identify them (it could go either way in the Narutoverse), then good - the entire process becomes much quicker and less painful. If not, well, you just breed your viable specimens together (lather, rinse, repeat) until, eventually, you stumble on a strain where none of the contributing parents had the gene you're looking to get rid of. Problem's gone.
Of course, this gets orders of magnitude more complicated when you consider how many potentially dangerous recessives there are in any given human's genome, but the principle holds.
There are only two problems with it. The first is, of course, how much it sucks to be one of the 'damaged' kids who get culled out in the process.
The other is that most recessive genes, when unpaired, actually have positive effects. The example that always comes to mind for me is the gene behind sickle-cell anemia - a person with two copies of the gene will suffer from the disease (periodic pain, strokes, etc.)... but, someone with only one picks up a serious boost in their ability to resist malaria. By breeding that gene out, that resistance is no longer present and the population's death rate from that disease will increase, possibly dangerously... in short, by the end of the process, all of your 'purified' descendants are going to be badly vulnerable to exactly the same things. If any of those pathogens or toxins or whatever get loose in the population...
Anyway, if I understand correctly, serious problems will usually take several generations to show up even in a family as closely related as the Hyuuga... I'd say that, while Hyuugacest would definitely be rolling the dice, the odds'd actually be fairly good for their getting away with it.
Letting the next generation do the same thing might well be a bad, bad idea, though.

Genetics defects can show up within one generation, if you get unlucky. A lot of the reason I don't like incestfic is because of just the implication of sleeping with a sibling/parent is emotionally very difficult for people, and no one seems to *think* of that. Most "normal" people don't say "hey, I'll have sex with my sister! Nothing could possibly be wrong with this!". And since Hinata does think of Neji as her brother, that thought would be there. I just... don't like incestfic. ^^;
