Actually, Space Marines from Deathwatch are superior to the Space Marines from Dark Heresy / Rogue Trader. That said, if Black Crusade does the Chaos Marines in a vein similar to DH/RT, I'd say it should be no problem to get a mixed group together. Naturally, certain character types will lend themselves far more to combat or sorcery than others, but with focus always comes a price - and whilst I'm sure that a mere cultist won't be able to boss a CSM around, I'm pretty convinced that FFG can come up with rules to make him a useful party member. And in the end that's all that matters.
And to be honest, I'd think a group with mixed hierarchy levels would be far more interesting than 4-6 Overlords all competing with each other about who is more awesome and get's to have the say. Rogue Trader and Ascension already give good examples on how to do it better.
That's not true. There's first of all one Space Marine stated out in all of DH/RT and that guy (who is Deathwatch) is from the second product published, which was written before they even had the corruption rules finalized. Those aren't the only thing from that adventure that are revised. The splinter rifles in RT have different stats as well. The only thing he's an example of is the early guess work for what Space Marines should stat out to be.
Ascension and Rogue Trader have different levels of authority within the group, but the characters are all roughly equal in power level. There are no rookie guardsmen in Ascension or Rogue Trader. Some characters are better leaders and some are better fighters but they are all high powered. There's going to be more variation in Black Crusade than in say Deathwatch where everyone is a Marine, but like Rogue Trader and Ascension everyone is going to be at the same general tier.
