You have to write custom Django middleware. You can start with this one and extend it to check if 405.html file exists and so on:

from django.http import HttpResponseNotAllowed
from django.template import RequestContext
from django.template import loader


class HttpResponseNotAllowedMiddleware(object):
    def process_response(self, request, response):
        if isinstance(response, HttpResponseNotAllowed):
            context = RequestContext(request)
            response.content = loader.render_to_string("405.html", context_instance=context)
        return response

Check docs if you don't know how to install middleware:
