+Maxxorlord: Seems reasonable. I'm going to presume that your limiting resource is Energon, which you can make/convert stuff into only with great difficulty? Anyway, you're accepted.

To jump in here even the Wikia you linked me to suggested that Soundwave etc. AUGMENTED their energon supplies with alternate sources. They didn't actually convert it into it, so you probably couldn't bring an inactive transformer back with it.
