Promethean Knights for Invasion

What do you guys think? If Invasion make’s a return. Would you like to see Promethean Knights playable alongside Spartan’s and Elite’s. I know Elite’s were confirmed to not be playable and whatnot. This is just an idea.

For instance imagine some map’s would be Spartan’s Vs. Elite’s, or Spartan’s vs. Promethean’s. Or Elite’s Vs. Promethean etc.
