I'd be worried about putting it on Blakley...
As a geographer, I'd be worried about the future existence of that island. It's located at the terminus of a delta, which for those of you who don't know, are places that are constantly changing in size, shape and elevation.
It's been there for years, yes, but the future of it is ultimately unknown.
PS: I know you were just offering it as a suggestion, I just couldn't help myself
