I think it is not possible to set Meta/Ctrl solely as a prefix for tmux. As for SuperSuper key, you need to set up both your tmux and terminal emulator as SuperSuper is X key and tmux works on shell. This answer explains better.
I recommend to set the prefix to something like Ctrl-aCtrl-a or Ctrl-sCtrl-s then simply bind , and . to move through windows.
# remap prefix
unbind C-b # Unbind default prefix
set-option -g prefix C-a
# bind comma and dot to cycle through window
unbind n p # Unbind default moving window key
bind , next-window
bind . previous-window
