Can they add Zen Sensei and Baron Von Bats to the Backyard Battleground?

I can't give you enough xp on this post. I get frustrated when I have to play more ops than I want to just waiting for the baron to appear so I can get that challenge. However, as a side note, yyou can always get the zen sensei challenge by going to the davebot and redoing the fireworks quest. (Sorry I've forgotten the exact name)
