Small campaign update request

Hey guys I have a small request for a campaign update in halo 5. When you play co op campaign you get the option to select which spartan to play as. I would like this feature to be brought over to the single player campaign. It would be nice to be able to play as buck or another spartan at times. Each spartan has different upgrades and they spawn with different weapons and have different dialog. Having all this limited to cooperative play limits player options. It would be a nice little update to bring these options to single player. Would also increase the replayability of the campaign. What do you all think? Would this be difficult to pull off from a programming standpoint? Would this be worth it?

I doubt this would happen, but I’d like to see it, might actually give me some time to try out the h5 campaign again and here some different dialogue.
