Hide body on node edit if user can't access input format The default behaviour is that a user can't edit a node when they don't have access to its current input format, even if they do have the edit content type permission. I'd like to just hide the body field in those situations. Does anyone know of a contrib that does that? (I'm only interested in the body field, but a more general solution would be cool too.)
Not really an answer, but there is AFAIK no way to change this without hacking core.

The check for this is directly in node_access() and can't be altered.

What you are trying to do is btw how it works in Drupal 7, see the corresponding issue.
