I am going to be so honest, there is no way I think Babylon 5 could be remade or added to. It had some bumps in production, but the actors were irreplaceable. I cannot imagine anyone other than Andreas Katsulas as G'kar. There can be no other Ambassador DeLenn except Mira Furlan.

It's one of those cases where even the flaws it had were so perfect and so human that altering it would nearly be sacrilege. I hope to any gods that still give a fuck that the corporations forget B5 ever happened so it can rest in peace. Because you know that if they try to do any corporate necromancy on it, it'll be a shambling horror that's nothing like the original.
