Ultimate Dolph

In this recent interview (2:41) with Michael Jai White, he mentions Dolph and Scott Adkins were supposed to be in a 'Blood and Bone' sequel a few years ago. I also found this old tweet mentioning a meeting about a sequel (possibly with Scott Adkins). Didn't Scott or Dolph in a recent interview mention they were supposed to star together in another film before Castle Falls (it probably wasn't this, but considering a specific title wasn't mentioned, it's plausible)?

That may have been interesting, while I'm not into most of martial arts driven movies these days, I really dug the spirit of BLOOD AND BONE when it came out and I'd like to revisit it.
