[BTAS] Do you think they ever rebooted The Gray Ghost?

In BTAS there is a fictional show called the Gray Ghost, and I'm wondering if there was ever anything expanding on this series.

Actually, there was a canonical DCAU Batman comic story about this.

As we saw at the end of the episode "Beware the Grey Ghost", the character saw a sudden resurgence in popularity.

Not too long after that a feature film went into production at a movie studio owned by Wayne Enterprises, intended to resurrect the character on the big screen.

The star of the movie was a new up and coming actor named Trystan Zale (read that aloud).

As a sign of genuine gratitude and respect, Bruce arranged for Simon Trent to make a cameo in the movie as a police chief and the Grey Ghost's confidant.

While shooting their scenes together though, it becomes apparent that Trent's acting skills have become kinda rusty, and he has a tendency to... drag out... lines..., and sound a bit hammy. Like his talents have gone ~~West~~ South or something.

Zale gets fed up cause Trent's acting keeps causing them to do take after take, and he snaps at Trent before storming off to his trailer.

Trent goes to Zale's trailer to apologize, and accidentally walks in on Zale in his true form- as Matt Hagan aka. Clayface!

As it turns out Hagan had invented the form of Trystan Zale to try and restart a new life and reclaim his acting career. 

He also turns out to be a genuine Grey Ghost fanboy like Bruce, and the role was basically his lifelong dream as an actor.

Unfortunately, since Trent found out his secret, he has to kidnap him and think of a way to get rid of him. Long story short, Batman rescues Trent and beats up Clayface.

The movie barely finishes production without its star thanks to some desperate behind the scene work. It's implied that it's a so-so movie, but Bruce and Trent's kid grandson like it, which Trent says is just fine with him then.
