Destroy the Old Guard and Oligarchs

I am trying to do a run where i take down as many old guards and oligarchs as possible.

Old Guard: Soll, Hawker, Garaci, other old guard judges, Valken (any other?)

Oligarchs: Tusk, Koronti, Mikael (any other?)

How would you go about doing that?

I thought about a Dictator Path with SSP where i jail Tusk, Koronti, and Mikael after the nationalization path. Purge the General Staff to get rid of Valken, and replace all Old Guard Judges. But i am failing at the Court when i try to pass my Constitution 6 votes No against 5 votes Yes.

I got Edmond and Garaci totally onboard, but can't see to get more than 5 votes. I need the SSP to jail Mikael, so no ACP and since i jailed Tusk and Koronti they can't help me either. Is there no way?
