My Gnus is configured with:

(setq gnus-summary-line-format "%U%R%z%B%s -- %n\n")
(setq gnus-sum-thread-tree-root "● ")
(setq gnus-sum-thread-tree-single-leaf "`->")

Viewing with this config is straightforward.

How about linked to root message with special marks characters and
add two commands/functions like link-threads break-thread
and let the user joining the two threads together.
