But that is already there (without keybinding):

    (defun notmuch-tree-from-search-thread ()
      "Show the selected thread with notmuch-tree"
      (interactive)
      (notmuch-tree (notmuch-search-find-thread-id)
                    notmuch-search-query-string
                    nil
                    (notmuch-prettify-subject (notmuch-search-find-subject))
                    t))
