Highly unlikely, especially since the White House has openly been against her actions from the very beginning.
Now the question is where does she get the authority to "officially" represent the United States in foreign affairs? The people didn't vote on it, Congress didn't vote on it, the President didn't approve of it, and to the best of my knowledge, it's not a special privilege of the Speaker.
So while it's hard for me to say her actions were/are treasonous, I do fully believe she willingly and with full knowledge exceeded her authority and should be punished thusly.
