I'm pretty sure this is not quite what you want.Place the beginning Clues on the stable (green diamond) locations instead of the red diamonds. That will give you a few more Clues to start but they won't double up. Don't let the investigators pick up the clues in their location but make them have an encounter first.
I think you're really looking for a complicated game of Clue though with a mythos theme.
