Classics Minicon teams question

As mentioned in the haul thread, I recently got Cybertron Metroplex, and I noticed he has spots for about nine million minicons to merge with him. I have two of the Classics minicon teams - Clear Skies and Dirt Diggers. The minicon that came with Metroplex (Drill bit?) has a weapon mode, though the Laserbeak that came with Cybertron Soundwave doesn't appear to have one.
I was wondering if the Classics had any official weapon modes as well. They all have the little round connector with the tiny peg in the middle and I can mount them on Metroplex like he's some kind of jungle gym, but if they can transform into weapons, that'd be even better.
