I disagree
Ba-humbug!

Sorry, could not help myself
I have to say that this thread started at a good time for me as I just received the last of the hybrids I needed if I was to ever field a 40K Genestealer cult force. I got these for AUS$30 so I can't complain about that.
Overall, you have to decide at what point the list will cover a Genstealer uprising. I think TRC does have a good point, the uprising happens in preparation for the hive fleet to arrive. Now it depends on what the timeframe of that is. If there is time where Marines will attack the hive fleet and then come to clean up the effected planets, the Genestealer Cult (if successful) would have had ample time to prepare the Imperial armaments. A Baneblade is not a Titan, so should not be to far different than a really big tank (I guess). If however they have not got a foothold and are still rising up against the planetary defence force, then they would definately be less organised at a time when help comes to save the day.
If I were to tackle this however, I would want Genstealer cults to be ingrained enough to have an effective defense to an attacking force and attack towards a defending one. Anything less organised is 40K (28mm) IMO.
