Sorry, but there's no way you can include John Roberts among the 6-3 alleged majority. He's proved his willingness to legislate from the bench more than once, most notably confirming Obamacare. At best, there would be a 5-4 majority, but John Roberts is not a textualist constitutionalist.
No way in hell.
And when you think about how GWB turned out to be a full-blown RINO, it's not hard to see how that happened.
