Ok, if I had my way, the Enterprise E would have been the 3 Nacelled GalaxyX from "AGT" 
But I know most people hate it with a passion
So, I would have settled for the Venture upgrade, which actually makes sense within the universe, since it was heavily used in DS9, and would have made a fine Enterprise E.
At the same time they could have updated the indoor sets to be more movie like while keeping to the original TNG designs.
To me, highly preferable to that hideous insect like Sovereign Class abomination.
