I think that would make matters worse.  AFAIK, AES-128 is considered to
be *stronger* than AES-256 these days.  A somewhat recent summary that I
found:

Difficult; the caps/urls are getting pretty long already how would you
encode this while not making them unmanageable?  Also, client support
becomes a non-trivial issue.
