Not precisely, Outer Heavan is just the singular, niche part of the Boss' philosophy he interpreted, and it's not exactly a utopia for the soldiers as much as it is both a home for soldiers disillusioned from their countries of origin, and generally acts as an anti-imperialist force in the world. Outer Heaven is a part of a bigger plan of opposing the Patriots, and eventually BB does realize the totality of the Boss' will, but that happens right as BB and the Patriots mutually destroy each other. If Outer Heaven didn't get destroyed, BB was probably angling to become a major geo-political force in the world to try and curtail the Patriot's influence and stop them from creating the MIC of that universe and prevent the implementation of things like the nanomachines son
in every soldier. Fighting the Patriots was basically the express goal of BB post-Peace Walker, and as MG1 and 2 showed he wanted to do so on a global level.
