Heck yeah, I will read an ongoing Batman and Scooby-Doo comic book

...particularly if it continues to be scripted by Sholly Fisch. This sounds like fun:
As early as the second issue, you'll see not only the first-ever team-up of Scooby and Ace the Bat-Hound, but also the first-ever meeting between Mystery Inc. and the Mystery Analysts of Gotham City. As an added treat for longtime fans, I've also expanded the roster of the Mystery Analysts to include a bunch of DC's classic detective characters. One of them, in particular, is a natural fit for the Mystery Inc. gang, but I doubt anyone will see him coming.

There are lots more surprise guest stars and cameos waiting in the wings for subsequent issues too. Some of them are members of the Bat-family. Some aren't. And there are some you wouldn't believe even if I told you, which I won't.
