Warhammer 40k mod trademark/copyright question

Hello at all, it has been a long time thats I visited this forum 
We(two persons) are making an Mod for Battle for Wesnoth, around 40% are done.
It is the World of Wesnoth in the dark future, where is only war ^^
So the elves will change to something Eldar/Protoss faction, undead to Necrons and so on.
Sure, we will NOT COPY the Units/Names of the Warhammer/Starcraft/Startroopers Universum, but you will see conformities in style.
We would like to name it Wesnoth 40.000
To be on the right side, I would like to ask:
We dont hurt any copyrights?
Here a image of the Space marine, you see we dont copy, we create a new style.
