Doom would have a hard time getting the Reapers under his control but it wouldn't be impossible. However, if Thanos enters this fight, he wouldn't let these "ignorant machines" run the show and would push them out of the drivers seat and become the main bad guy in this fight. The Reapers are a force to be feared but they will not last when the bigger, more powerful forces enter this.
