Tips for killer lens flare removal

I have a clip shot on 35mm film that is a time lapse of the sun rising on a statue on top of a building. The statue is a golden eagle. Unfortunately, there was a lens flare on the left side of the screen that flickers the whole time.
I first tried to suppress some magenta (or shift it), but the flickering remained noticable.
I then started painting out the frames where I could, but the gate weave made the cloning noticable. I stabilized the footage to remove the gate weave and started painting again, but because of the time lapse the lens flare may be gone but now the brightness flickers (since I'm cloning from 4 or 5 frames away)..
I may play with getting ONE good frame and CCing it to match the other side (tracking for gate weave and matching grain)..

You know what I would be tempted to do? Grab the last frame and fake the sunrise with an animated CC or two. It looks like it would key easily so you could separate foreground and background to do a more convincing job. With the original as a guide, you shouldn't have too much trouble and your secret will be safe with me, I promise.
I tell ya what else, that .mov crashes Combustion in a heartbeat. As soon as I select it, down she goes.

Hey bones,
I ended up painting 3 clean frames at about 30%, 60%, and 100% of the timeline and CCing them to match the time lapse exposure, the cross-faded from one to another. That way I could have more control over the contrast and highlights as the lighting changed..
That is weird about the movie crashing c*.. I loaded it up after reading your post, and sure enough it crashed mine too.. Show that to the boys over there behind the curtain, maybe it will help in figuring out the combustion/quicktime anomolies.. I created the it by loading a normal uncompressed combustion-rendered mov into quicktime pro, then exporting it as a h.264 two-pass mov..
