I think there is a misunderstanding here. In Higurashi Rika doesn't "select" her Kakeras. What happens in them is more of a gamble than anything you never know what to expect. All of the scenarios start with the same circumstances it's how the environment changes from people's choices that make them into "different kakeras". In a way Rika and her friends actions wrote the story.

How that applies to Umineko is probably a different thing altogether. I just wanted to clear that up though because I don't think selecting a scenario that suits the time has ever been part of the Kakera concept.
