tim burton would have i think tried to make a only slightly lighter batman film for his 3rd movie. kinda like goerge lucas has done with both star wars OT and indiana jones, first one is the awsome classic, 2nd is the dark 2nd chapter, and the 3rd is much lighter then the 2nd one but ties everything together. but i doubt burton would go lucas bright for his third. for 2 face he would have billy dee williams of course and i bet he would have rocked. as for robin and batgirl, mr freeze and poison ivy, forget it, burton would never include those characters. he has already expressed how he never really thought robin worked well with a dark character like batman (totally true!) and never really wanted him. Thank God. i could totally see burton doing scarecrow, scarecrow is so much more of a tim burton bat villian then the one nolan did. he would have made scarecrow AWSOME and scary, and would have hired someone who REALLY embodied scarecrow and the insane look of the character, like jeff goldblum, who everyone agreed with when it was still a rumour.
