Ok, well, it would sort of be like the Masterpiece soundwave, the one that uses MP Prime and actually has an MP3 player in it and stuff. But this wouldn't be an MP Soundwave, it'd be an ALT Soundwave. It would still use Prime as the base, but the alt mode would be a car carier ala Magnus, and the whole thing would turn into Soundwave, and the ALT Tapes like Ravage and CO would fit inside him in vehicle mode. But I don't collect ALTs, so really this is just insane rambling....
