Lens effects commandline tool?

[Ihno]

First off, the new glare/bloom effects are f****** awesome! Its like a magical "make it beautiful" button.
That makes me wish I could run it on a already comped animation. Or simply on the raw renders, but after the rendering on existing animations.
Would it be possible to get a command line tool that can process animations or would you have to put a huge amount of effort into it?
