[Harry Potter] Can you horcrux yourself?

At the end of Deathly Hallows, Voldemort's killing curse destroys his own soul horcrux on Harry, rather than Harry.

This implies that if you stacked soul horcruxes on a person they'd be immune to at least one killing curse per soul portion.

Do you think its possible to horcux yourself with multiple different souls, in order to become (relatively) invulnerable? 

Could you do it without fracturing your own soul? (like Harry Potter's situation)

How would you do this?

You probably could do that, but what would be the point? Instead of immortality provided you keep your horcrux hidden, you'd just end up with an extra life should you ever are mortally wounded. It's far more beneficial to make your horcrux something you can keep in a different location to where you are.
