I am guessing Chloe is a goner at seasons end of Smallville...but wouldn't a "Watchtower" series be a good spin-off? By day Chloe gets back to a normal life or so it seems...but by night she is coordinating superheroes and helping them save the world...these could include a few DC characters we haven't got to see much of in live action. Would you watch "Watchtower"? It of course would Star Allison Mack as Chloe Sullivan.  I voted Yes...though I don't need my Chloe/Allison...would be fun to watch.
