Is removing the aliasing filter really such a smart idea?
Alas none of the above is possible with an interchangeable lens camera, a mechanical optimisation for one lens would inevitably make it far worse for many other lenses. and a software optimisation might go somewhere towards solving the problem but only for lenses from the makers own catalogue no doubt.
But there is a twist, should you actually take the time to sort all of the above issues then you may well find yourself being very grateful for that AA filter.
The marketing is aided and abetted by the fact that camera reviews pixel peep files and at a 100% pixel peeping view the non AA filtered file may look just a little sharper, and sharper means extra sales!
