Amaya already does item 1.

Item 2 suggests physically removing tables, but you would actually need 
to turn td and th elements into div (or keep them and set the CSS 
display property.  As such changes would change the DOM, you would have 
to do this just before rendering.

Also, this list is far from complete, e.g. my biggest accessibility 
issue is layouts that fall to pieces when you disable author font sizes. 
  These tend to happen most when people are trying not to use layout tables.
