Project Talk Transformers/GIJoe Combaticons

Im looking to repaint some GIJoe vehicles in to Combaticons. Need help coming up with what vehicle to use for what bot. I kinda what the four vehicles to be around the same size and have Onslaught the biggest. Need some input guys


Onslaught , Rolling Thunder?
Brawl , Hiss tank or MOBAT
Blast Off , Crusader Space Shuttle, Avernger scout craft
Swindle , Vamp
Vortex , Dragonfly

Onslaught strikes me more like the Thunderclap.
Brawl should definitely be a MOBAT.
Blast Off as the Crusader.
Swindle might look better as the Desert Fox.
Vortex ends up as a Dragonfly by default.

Onslaught , True Heros truck/Missle laugher
Brawl , MOBAT / similar sized tank
Blast Off , Make life easy on yourself & use a Hess Truck Space Shuttle or a Sky Links transformer, unless you can get your hands on some 80s toy shuttles closer to scale.
Swindle , Vamp (any version but updated POC style would look best)
Vortex , Dragonfly or True heros appache depending on the scale you want
