Without Jerry Orbach the show wasn't and still wont be the same. Plus S Epetha is on Chicago Med and I question if Sam Waterson would return. The only detective paring that might work would be Chris Noth and Jessie L Martin perhaps?? IDK.
That's the same guy behind the Tonight Show Jay/Conan kafuffle as well. I don't know about this. The beauty of L&O the mothership was that the episodes were about the CASE, not the characters' personal lives and I don't trust Wolf/NBC not to screw that up. Besides, it's been over a decade. I say just leave it alone, but who knows.
