I disagree with your characterisation because my impression is Ray was already heavily involved in restructuring the org prior to 75. He didn't just wake up in 75 and say "I want control of the theology". By his own account in CoC, the GB was becoming more hardline; he had already essentially lost the power struggle, whatever it entailed. The shift to GB meant Freddy Franz has already been disempowered in a sense, anyways.
IMO Ray portrays himself as fundamentally responsible for initiating the shift from Presidency to GB in CoC. Obviously there would have been many people pushing towards that at the same time, but it gets written down in CoC as if Ray "did the research" and then officially triggered it. The GB officially appears the same year Ray joined it - 1971.
Your characterisation doesn't square with what Ray says in CoC. Ray was definitely a player, but my impression it was in the late 60s / early 70s. By the late 70s, the writing was on the wall and I don't think being the successor to his figurehead uncle meant anything. Plus you impugn a certain cravenness to his actions which I don't think is accurate; he could have easily towed the line if all he wanted was "the position".
