I think it's time for a reboot, although I think the Bumblebee movie will show whether or not it's possible to do good movies in this universe. If we do get a reboot I'd like to see: 1. More realistic, simpler robot designs that homage the 80s show while still having their own fresh flair. 2. More intelligent humor, less crude humor. Less/no bad language and extreme violence. (Keep language and violence on about the level of A New Hope or The Force Awakens.) 3. Nothing on Earth pre-1900. (no knights, pyramids, etc.) Everything should take place in a world with some sort of technology and vehicles for the TFs to turn into. 4. Better human actors and characterizations for the humans. No existing human characters from other incarnations of the brand (No Sam/Spike Witwicky, Carly, Miko, etc.). Less/no military involvement and humans fighting against the Transformers. More 'everyday' human characters. 5. Streamlined origins (Quintessons built Transformers, they rebelled, had a war on Cybertron and came to Earth). Maybe Unicron, but no Primus or 13 Primes. 6. Less/no plots that revolve around ancient McGuffins. 7. Keep the idea of TFs scanning vehicle modes. Also keep integrated weapons and the idea that they can deploy weapons in vehicle form. 8. More variation in alternate forms (less modern supercars, more older/commonplace vehicles, and also more non-vehicle tech.) 9. No Jablonsky, different style of soundtrack (maybe something more like this). Work in an instrumental version of the classic theme song. And certainly no Linkin Park. 10. Less/no city-destroying battles. Smaller scale stories and more secrecy around the Transformers. Maybe they're more of a myth among the population than a known presence. Edit: Honorable mention: this one's going to be controversial, but I would honestly enjoy all the TFs to have non-humanoid face designs that don't emote much (if at all). Let them express personality through tone of voice and body-language. Think K-2SO from Rogue One. This eliminates the creepily-complex-look of the current faces, and the liquid metal look (which probably wouldn't translate well to live-action.) Optimus would be easy, since he already has a faceplate. I've never really understood why robots need mouths anyway.
