No no no no no no no. This would be a massive waste of development time. If/when they make another adjustment to these instances they need to make the only change that actually fixes all the issues. They need to turn them into solo instances. You go in with scions and/or GC members. Strip Ultima out to be an 8 man trial completed afterwards, and then finish the 2.0 story with another solo instance for the Laha fight(amp it up if you like). Since these are no longer group instances, they can set the cutscenes to be skippable again if they want since it will no longer be an issue of other players pressuring new players to skip. Then they can delete the MSQ roulette since there would no longer be a niche for it. Problems solved.
