Just beccuase it's not for profit doesn't mean it's illegal I'm afraid. Stealing a car and adopting it as your daily drive is still against the law, even if it isn't for profit.
The yellow eight-pointed star is fine because that is representative of more things than chaos undivided (I'm fairly sure Hindus or maybe Baha'i use it, but don't quote me on that and correct me if I'm wrong), but the Black Legion symbol is GW copyright and they can propably get you for it I'm afraid.
You'll notice that Bolter and Chainsword, Warseer and Dakka Dakka only use icons that are suggestive of the hobby; this is to prevent them getting C and D orders.
You could try looking for a copyright-free image on a search engine like
Creative Commons for images they can't get you for, but logos are notoriously difficult to find.
If all else fails, you might have to just stick with your eight-pointed star I'm afraid.
