As I recall, the Canon 5D is one of the few cameras where a successful AA filter removal is not possible. An AA filter is really two filters, a slab of LiNbO3 that spreads the imave vertically, and another that spreads it horizontally. The 5D reduces the filter stack height by using the vertical LiNbO3 filter as the cover glass for the sensor. So, an AA filter removal will simply result in strange looking "vertical only" aliasing. Even if you use an aliasing removal plugin, like "demoirize" from P1C1, you can't really fix 5D weirdness.
