Made some calculations:
So, the video has 756 frames, 56 of them are just the intro and outro, which could be just used to put something ourselves (thought of putting 8ch's main page in the intro and 8ch + the cup's logo at the end), this means that we have 700 frames that can be edited, and since we should have 32 boards when the thing starts that means each board has 21 frames, which should be pretty easy to do, especially with boards like /bane/ who also worked on an animation.
