If your main aim is for a television style feel in terms of a G1 cut, what about reworking it into something of a 'pilot episode' for a live action series in the G1 style, sort of like what was done [by a fan, Jack Marshall] with Star trek 5 as a pilot for cancelled follow up series [to star trek TOS]. If you haven't seen this i'd recommend it - if only as a really good guide as to break of a film into distinct 'acts'. Maybe you could have the classic scene transition of the autobot logo flipping to the decepticon or vice versa - using the theatrical style brushed metal logos...

Actualy I'd be tempted to work on this idea myself. What are your thoughts?
While discussing the movie with a friend he said "it needs more star scream", Maybe you could achieve this by simply having him be more vocal, with that classic whiny voice...
In the end it's your edit, I'm just putting it out there. When you are ready I'd love to review it for you and give you feedback.
