Where did you find that 6 months deadline ? It is actually one year.
To avoid abandonment of GC, the permanent residents are required to re-enter before the completion of one year from the date of departure.
PRs can stay beyond one year without abandoning the GC by obtaining re-entry permit proposing valid reasons for the lengthy stay. This re-entry permit rules are similar to AP. It is ruled out in your case.
One thing I have to mention is, after the Boston event, there have been a lot of additional CBP questioning to those who are re-entering after 6 months staying out of the country. I don't know if this is still in practice, but that was the reason which has forced me to cut short my stay.
Otherwise you have one full year to go.
