Yes, all operatives of the BPAP will be put under strict training regiments to hone their powers. Animal will oversee this training for the most part. As well, there will be a psychologist working with the heroes to make sure they are mentally prepared for this line of work, as well as to strengthen their pride whether they be titans or regular humans. So yes, I plan for all of the group to receive new powers from hard work and training. They will also be trained in other areas including hand to hand combat and firearm training, as well as a written exam. So they'll certainly be pushed to become stronger. That's why I say not to make them too powerful now. And yes you can replace Artists posts.
