There is no provision in Wireshark for showing the raw dissection result (the protocol tree) differently.  This is 
intentional - dissectors are supposed to exist, and work, independently of any particular UI code (that's why TShark 
works).

If you want to show information in some *other* form, you should write a tap with a GUI.  See doc/README.tapping for 
information on writing a tap.  The tap's per-packet function is passed an epan_dissect_t pointer (which includes a 
pointer to the *entire* protocol tree, not just the subtree for the protocol being tapped) and a const void * that 
points to whatever data the dissector passes to the tap.
