The OP began this thread asking for thoughts on his campaign. If he just wants to -
"In summation, I'll play 40k if it please me and I couldn't care less if you think I'm doing it wrong. You play it your way, I'll play it mine."
- then why bother asking our opinion in the first place?
As for your talk of following the setting like mindless sheep, that is blatantly ignoring, and frankly insulting, what most of us GMs here that do follow the lore are actually doing.
We place ourselves in the mindset of another world, one with rules and boundaries that we follow not because we can't come up with alternatives but because it challenges us to approach a subject from a different perspective.
My interpretation of the lore and what is canon may vary compared to others and I take liberties in my own games when it comes to topics the setting is vague on.
As for my statement, what exactly are you disagreeing with. The fact that the OP is cherry-picking from the game setting? Because he is. Or the fact tbat what he is creating is no longer recognisable as 40k? Which again, is a true statement.
