I still think Indy could work in the animated realm. Maybe a video game that doesn't suck or an animated show on par with the Batman animated series.

I enjoyed a few of the Indy novels that were written in the 90's. They weren't as good as the films, but it gave me more Indy than KOTCS did.

I think Indy would make a very entertaining cartoon.

That way, if Harrison Ford would be opposed to it, you could get somebody to sound like him. They already use his likeness in every video game, novel, and comic they produce.
