I've been looking into the game files recently, and although I haven't looked into abilities yet, discussion with other modders make me think this is possible.

However, it defeats the purpose of the Commando role being specifically built towards damage, and non-elemental at that. Use En-Spells (such as Enfire) to get elements on a Commando, and you can double your damage input if the enemy has a weakness or if you use Imperil.

While this is true, I would prefer Commando using the melee skills and Ravengers staying out of the way as they usually are not able to withstand attacks when they run up and become a priority for direct attacks or place themselves right into an AOE. The AI doesn't understand proper placement on the battlefield. So these skills are really only useful to Hope and Sazh in ravenger.
