I'd say it might be in bad taste to kill her off for the sole purpose of spurring her man into action, but let's be honest... she only exists to begin with to complement Thrall.

I sure hope he won't kill her and that isn't because I like Aggra all that much (don't really care about her)
The main reason is that with the current developments on Varian's side, killing Aggra would actually make Thrall and Varian the exact same guy but in different colors. I don't want that.
Besides I can think of a more fitting kill from Garrosh that would rouse Thrall: Drek'Thar. Sure the guy us is blind, old and crippled but he also defied on of Garrosh's commanders, is a powerful shaman and above all he's Thrall's first tutor in the shamanistic ways of his people and is a connection to his parents.
In all honesty, Aggra and Thrall's kid get no love from me.
I see their son going down Med'an's Gary Sue path at best. Garrosh murdering him/her does give the Horde more reason to doubt his sanity and judgement. Tragedy in stories is needed sometimes, and the last time I remember that occurring was
Old Blanchy's demise.
On a personal level, I'd love to see Aggra dead... by any means at all. But I also think that if Garrosh kills Aggra, he might be "cool" to most of the Horde players, as most of us want Aggra gone too.
That said... not gonna happen. I don't know why, but I can't see Blizz making that happen.
Nor can I see Thrall being the one to 'unseat' Garrosh. Nor do I believe it is the Sha corrupting him. I think that it really needs to be JUST "Garrosh is just a giant d*****" kinda deal.
Ultimately, the being that actually kills Garrosh (after we weaken him, of course), is likely to be Rex.
Though Aggra did 'bring Thrall back' from that whole Elemental planes dilemma with his inner self (or at least I think this is what it was), it really didn't have as much impact on me personally. Hence, no love.
I want Garrosh to kill Aggra and boot that child to the nether but, unfortunately, i don't see it happening.
This would actually make Garrosh likeable, though.
HOWEVER, her voice is annoying as hell. I find that's the entire reason I don't like her as a whole. Nothing to do with her character, just that annoying voice.
