Hm, that's more difficult. It would be possible if the generator includes redirects but you can't be sure. pagegenerators -start does not include them for example. And in addition filtering should be done prior on server side instead of retrieving a lot of pages and discard them later. The old Combat implementation is just like -start but for redirects only. Implementing as a partial filter is not so easy; maybe this is not for good first then.
