I think the elemental would have to be it's own mech. If you choose to pilot it, you choose so. I think that is the only way it would be accepted.
The only way I can see people accepting elementals is as a Point (5 of them.) If the one in the middle dies, the player is out of the match and the remaining elementals disperse. This would allow the player in the elemental to field a few small lasers instead of just one. While they would be hard to hit, even a glancing blow from a large laser would be devastating to them. I don't think they would be OP.
I think it would add flavor to the game.
*Edit* A Point of 5 would weigh 5 tons, making it a nice place filler if we ever get a weight limit mode. Although I know in the lore and in games past they are capable of a lot of destruction, I think their place inside MWO would be best as that of the "tonnage filler" for that last 5 tons on certain team comps. Relatively weak, but fun to play, and worth 5 tons.
*Edit* Fixed "Star" (25 elementals) to "Point" (5 elementals). Thanks lore masters, I'm learning =)
