Possible, yes. But usable, I'm not sure.
My guess is that you would need to create a custom mini window that just re-displayed the information from the actual party window. Performing actions in the mini-window would trigger the actions on the actual party window. So for example, sliding all-in on the mini window would then display the appropriate party window and perform the same action. To me this seems too chaotic. But maybe I am missing something and there is another way. I guess we'll wait and see.
