One of my odder random thoughts recently was the idea of Henry James and Ernest Hemingway rewriting each others’ stories: A Hemingway version of “Turn of the Screw” and a James version of “The Killers”.
This reminds me of an anthology concept I've been noodling with for a few years. I don't have the time or funding these days to the editorial work to organize this, but I've always thought it would be funny as hell. Basically, it would be titled something like Crossdressing, and would feature about a dozen or so authors writing in each other's styles. Could be parodies, could be more serious homage.
This works best with authors with fairly distinctive voices, but I think it would be hilarious to see Jeff VanderMeer writing as Ken Scholes, and Ken Scholes writing as Mary Robinette Kowal, and Mary Robinette Kowal writing as Charlie Stross, and so forth.
Someday I'll have an entire bookshelf of anthologies that never were.
