Yep, sure, but since its a private group is like anyone is free to scanlate it if they feel like doing it. The unspoken cortesy that rules the scanlation world says that if a group has pick up a project and is doing a decent work is unproper to pick up the same one. Its more like a waste of effor to do the same thing twice although anyone can do whatever they want I think. But if you go private, be private and leave the rest do what they want.
