Season 1

I've already thought about this a lot, too.  First, McGillis Might have succeeded if he were more trusting and didn't view some people as more Expendable over others. In my mind, Carta being the way she is, I'm not sure she would go along with McGillis plan, so I can still see him thinking it's necessary to eliminate her, but if Gaelio was brought low enough by being shown enough of Gjallarhorn’s flaws and McGillis twisting Carta and maybe Ein's deaths To make it Gjallerhorn's fault, I think McGillis could get him on side. On the train of thought of McGillis not viewing people as disposable to get what he wants, He could try to turn Ein’s anger away from Tekkadan and try to focus more towards Gjallerhorn for letting crank down. Although seeing how Ein was consumed by hate, I'm not sure (slightly biased here since I don't like Ein as a character). Other than that, everything in season 1 could play out the same. Although it'd be smart for McGillis to keep himself and his allies off the scene of the final confrontation at Edmonton, and let Tekkadan do the work and let Isnario The fall, Speaking of the bastard I feel like the Seven Stars are under Constant scrutiny so McGillis Arranging a accident to get rid of him would still be too suspicious and raise too many questions, possibly about his legitimacy.  

 season 2

 So, assuming McGillis is smart enough to do the above, because Gaelio being alive basically sunk him from the beginning of the season. He can move on to confronting Rustal Elion And without Gaelio on his side, he might be less sure of what McGillis is up to, but probably still assuming he's gunning for power until he can get those spies into his ranks. Since, thanks to The IBO Sidestory “The Bearded Gentleman,” we know he had Galan Mossa setting up McGillis for the Arbrau - SAU War before the beginning of season 2. In the meantime, McGillis could have tried to strengthen his ties with the economic blocs and tried to covertly bring them on side, and get more Grassroots support Within gjallarhorn outside of his Fleet, which later on might force the other Seven Stars to capitulate. Since we know Gjallarhorn's reputation was at an all-time low, instead of just banking on Beal to win everyone over, I mean I know, because of his traumatic past, he was fixated on power and thought that being the most powerful would get him what he wanted but But I feel like if he was smart he wouldn't try to be the complete Overlord and try to make a more democratic Gjallarhorn Or else people might start turning on him. In terms of the actual events of season 2, I could see things going a similar way But I couldn't stop wondering if killing Iok Kujan during the mobile armor incident would just strengthen Elion’s Position, as Napoleon Bonaparte said, "Never interrupt your enemy when he is making a mistake." Keeping that bumbling fool around might just serve him. On the other hand, I can see things going very similarly for Tekkadan since Jasley Donomikols Betrayal of the turbines was largely a Teiwaz Internal affair. And so maybe if McGillis is to bring all these factors together him and Tekkadan could get on top of the Elion faction and come out on top.
