I think that Cliffjumper would have been a good replacement for Jolt and Dino/Mirage...think about it, in ROTF you see him with the Autobots in their highway driving scenes and Optimus, him, and Bumblebee rescue Sam, however there would be an extended fight and during that fight, Bee is knocked out cold. After that Cliffjumper saves Lio and Mikayla (however you spell it). Then the forest scene cuts in as usual but once Starscream and Grindor attack, the scene cuts to Bee waking up and rushing to Prime. The forest scene continues and Bee arrives just in time to see Prime die. Bee is distraught at this and the scene plays the same but Cliff comes with Bee and the twins and acts as a sort of counselor to Bee and the film carries on as usual just with Cliff in the scenes then, when Bee and the twins are attacked by Starscream, Cliff stays behind and fights him off, then the film continues on as usual until Rampage dies, Cliff then finds his way back, helps Bee kick Rampages butt and drives Sam's parents to safety. So the scene plays differently as Bee is protecting Sam the whole way to Prime until the scene where Megatron shoots Sam, Megatron attacks but Bee tries to protect Sam, however, Megatron quickly disposes of Bee, throwing him to a nearby pillar the scene then plays out as usual but Bee is now distraught and blames himself for two friends deaths. Cliff then appears and comforts Bee then the scene plays as normal. Now DOTM, he does everything Dino / Mirage does and instead of Sam killing Starscream he does attracting the attention of some Decepticons and triggering the prison scene. However he dies in the prisoner scene fueling Bumblebee to kill Soundwave and the other Decepticons hostage takers. Then we cut to the end of the film where we see Ratchet comforting Bumblebee over Cliffjumpers death as Optimus Prime begins his final speech that ends the film. So, what do you guys think???
