I actually think connecting the plotlines like this would make it feel simpler, not more complicated. Human brains are good at retaining information when it relates to other information; we’re less good at remembering multiple pieces of unrelated information (thus the existence of mnemonics, for instance). Having a moment where the audience goes “ah, that’s why I was being shown four different things” will - in my opinion - make those four endings feel less scattered and narratively chaotic.
