Maybe but either way a mod will never be able to achieve the fluidness or stability without sacrificing gameplay elements that the base game could achieve. Also if it's done via mod it's likely that you won't be able to play other mods co op.
I'd assume they could look into having games hosted by the players kinda like how paradox games tend to do it but I don't know anything about how that works so I won't act like it's easy or anything. I also did stress that it shouldn't be a priority right now as the base game does still need a lot of work.
