RealURL cannot. But I think you can do it with mod_rewrite! I did not test anything below and most likely it will not work if pasted as is but it should give you the idea:

RewriteCond %{REQUEST_URI} ^/topics/([^/]+)/([^/]+)/$
RewriteRule .* /topics/%1/%2/%1/ [L]

This repeats the first segment once more.

You will need to generate a link without the second segment and add a bypass to the last fixedPostVar. Bypass will not encode it if it is empty, so you should get a shorter URL.
