Let's be honest, it would be relatively similar in a sense that it would practically be a Star Wars version of Military Role Play.
Unfortunately, I find that it would be a poor choice. In fact, I believe it to be poor choice because it'll allow people to play as droids, although it certainly would seem rather fun and indulging to be B1, B2, or some other droid it would take a lot of development to further the process in the future. I've visited servers before that follow this format and quite often a lot of people tend to not role play well as droids, but equally as well in their clumsy-ness.
MRP is rather a two sided team death match with the size of teams differing. increasing and decreasing at certain times. Does a game mode in which it is a side of Clones and Jedi vs. Droids and Sith sound any different? The only way to format such a game mode would have to be equivalent to that of MRP. Let's be real. ๐๐
