Bullshit. The manga deviated everywhere where the anime totally fucked up. Characterization issues, pacing issues, motivational issues. Characters surviving that died before.
Ichigo and Goro switching places was an important factor for her opening up to him and him proving himself to her: If the manga goes the same route of pairing them up, it will be far more believable.
Alpha surviving means that she will most likely play some role, considering it's a concious choice to kill off the fodder nines long before anyone died in the manga and instead keep her around. Not saying she won't die, but something will play out very differently.
I presume it will also skip over most of the Kokoro drama.
