With the K1, no!!!!
The ONLY person who she AOS through is the original petitioner.....as she is divorced from him and now married to you this is now a moot point.
The only 2 options she has is:
1) file vawa so she can get a GC herself due to abuse (not frivolous- no false accusations, and abuse must be thoroughly documented/proven to hold any water), but Im not sure whether this is possible now she is re-married.
2) Return to her home country and then you apply for a spousal visa to bring her back over to the US.
What specifically did the Immigration Attorney you talk to say about the 180 days?
Once the 90 days on her I-94 are through, if she hasnt submitted her AOS (getting married within this time doesnt make a jot of difference, its the filing of AOS which matters) she starts accruing out of status presence/overstay. Once she hits 180 of out of status presence, then once she leaves the US to persue a spousal visa, she will be slapped with a 3 year re entry bar (360 days of overstay= 10 year ban).
Had she still been with the original petitioner, then should she wish to go through AOS past the 90 days on her I-94 then she would file the I-130......however, you are NOT the original petitioner therefore this does not apply.
