I've heard it's hard to to get settlers to show up at Spectacle Island. I know they could be spawned through the console and what not. But wouldn't it be cool to build a bridge from Spectacle back to the mainland? I think it is Warwick Homestead that is right on the coast near the Island so those two settlements could be connected by the bridge. Probably not an easy thing to do but I think it would really be fun to be able to build such a long bridge and over water and then be able to walk across.
