I guess it all depends on who the writer is and what characters you'd like to use. There is no harm in asking though, so I'd suggest just reaching out to them. Just make sure that you respect whatever their answer is and I'd even suggest letting them see wehat you come up with before you post it anywhere.

Also make sure that you credit them as the original creator.
