Killer of Killers, the Series, starring Dustin Clare?

With the successful completion of the Killer of Killers sequel imminent, and the third installment being planned to be written this summer or soon thereafter, it's turning out to be at least a three volume series. Should I call it the Killer of Killers series? Or the Trent Smith Saga? Or what?

Whatever I call it, it would be a great series on the STARZ channel, which had already made some great series. And seeing as how it had Spartacus with Dustin Clare, I think that would be a perfect venue for the Killer of Killers series, with Dustin Clare playing the lead role, Trent Smith, the world's greatest martial artist. And if Amber Heard is unavailable for the female lead Samantha Jones, then STARZ already had an actress, Ellen Hollman, who played Dustin Clare's love interest in Spartacus. Pairing the two together again in Killer of Killers would be sweet.

And a lot of those actors and actresses from Spartacus could find roles in the Killer of Killers series. Oh, what a dream come true if it were to happen. All authors have dreams like that. Game of Thrones,  after all, was a series of books. And they got made into a TV series, albeit by HBO, another STARZ-like channel. And it turned out great.

So when I submit Killer Eyes, my question is what should the subtitle be? Book Two of the Trent Smith Saga? Volume Two of the Killer of Killers Series? That is the question I'll need to answer and very soon. Because the completion of Killer Eyes is going to be very soon. Any suggestions? Let me know. Thanks.
