Could Deathly Hallows refer to Harry going beyond the veil.

Okay this is a wild theory but please bear me out.

Why did Sirius have to die by going beyond the veil, if he needed to
die so that Harry could learn to support himself why didn't JK Rowling
have Bellatrix Avada Kederva (sic) him?  Could it be a hint that their
is something important beyond the veil, from what I understand the two
way mirror is going to be important again, perhaps Sirius will find a
way to make a new connection to the mirror left behind and tell Harry
about some key to defeating Voldermort beyond the veil.

So this seems a bit rambling but I am just randomly throwing ideas out.
