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.
