I figure the twist you get this time is to "Captain America" Bumblebee. Have him wake up in the Beast Wars. Original Beast Wars was pretty sloppy with its G1 connections to a point where Starscream's ghost not only had to be a time traveler but had to be a ghost a second time since Starscream was alive at the end of American G1. I always thought it showed bizarre restraint that JG1 never just brought in Starscream between Headmasters and Zone. They brought back a bunch of dead bad guys and killed off a bunch of bad guys but Starscream literally could have waltzed in. The only reason he was dead in later manga and such was because Beast Wars said he died again. I'm not sure how much you can improve on MOST of the BW toys while being faithful to them. But I think the show had good dialogue (deliberately cheesy), characters, and acting with animation that dated worse than G1 and a plot that seemed to have less planning behind it than G1.
