I think you are way off with a few of those names.
You list Locke based on Tweets and rumour. When was the last bad Tweet from him? It was the Tweet about being bummed that Iro didn't get the coaching job (as far as I am aware), which in my opinion was not bad or offensive at all, but simply voicing his disappointment for his preferred option. It gave no reflection on Matt Elliott or his ability to coach. The rumours are wild and unfounded right now. ME stated months back, when the Tomkins talk happened, that he had big plans for Locke in the future. It was also rumoured that he told Locke to make a play for the 5/8th jersey if he wanted it. All of the talk about him leaving is pure speculation from media who cannot think outside the box. Perhaps the club intend on using Tomkins in the halves, or Locke, or even shift Locke to the wing, as many have suggested. As far as I know there has been nothing from Locke apart from a Tweet a few weeks back saying he wasn't going anywhere and loved being at the club. Dean Bell, and I think Elliott have both responded to questions saying Locke is wanted, but if he feels he needs to move on, they will allow it. In isolation, that could sound like they are prepared to ditch him, but if the reporters are expressly asking about Locke's future (as I expect is the case), then that answer is the only answer they could give.
Godinet is another that seems a little out of left field to me. He has never shown to be a part of this bad clique that has appeared. He has actually been labelled as nothing but dedicated, from what I have heard. Even with depth, I would imagine the club would be keen to retain him, at the very least, as a good leader for the Vulcans, and a good role model for the younger ones moving up to NSW Cup from U20s.
Carlos, perhaps, but I doubt it. There is no talk of attitude with him, and ME has pointed him out as a future star. I don't think you would go from that to dumping the guy based on a limited number of appearances in a foreign position. I would imagine the first thing ME would do was trial him in other positions at NSW Cup level.
Ikahihifo is one I feel strongly won't be in that group. He may not be a first choice player, but if Packer is gone (as is expected by most), Matulino is making sounds like he is unhappy at the moment, and Gubb is just digging hole after hole to bury his career, then I believe that Seb would be crucial depth for the front row.
I believe the group is made up of
Packer
Sam Lousi
Sione Lousi
Gubb
Taukeiaho
and possibly Mateo (though it could be Matulino).
I have had a sneaking suspicion that Mateo is a shit stirrer for a while now. I mentioned quite some time ago (before Inu left) that I thought he might be a trouble maker. Inu had been dumped by a few coaches, and had spent his whole career alongside Mateo, who has had his own issues with Twitter and attitudes toward his critics. Inu left, and his problems seemed to clear up. The same issues now appear to be ingrained in a wide group. Is he the cause?
