The fifth amendment?

Might a fifth series of Blackadder be on the cards? If the Sun is to be believed (and let's face it, it almost always isn't), then the answer is yes. Speaking as an enormous fan of the previous four, especially Blackadder Goes Forth, I sincerely hope it doesn't happen, given the calibre of work churned out by co-writers Richard Curtis and Ben Elton in the decades since it last aired. Surely Stephen Fry and Hugh Laurie, at least, have more sense than to think reviving it would be a good idea?
