[WH40K] Would it be possible to deliberately combine Chaos gods?

So I've been putting some thought into the Chaos gods.  We know they are the impressions of dominant emotions upon the warp, and are continuously fed by these emotions.

But what happens if a large body of people, highly psychic and deliberately trying, focuses on combined emotions of two or more of these gods? By this, I mean what if a cult (and it would have to be huge, I know, as in galaxy-spanning huge) that celebrated elaborate plans to sustain perverse pleasures? Or a cult devoted to spreading a virus which causes victims to build their rage and eventually rupture in a shower of blood?

Would it be possible for this to draw a bridge in the warp between Chaos gods, and cause them to combine?

Unless they are directly controlling the flow of energies in the Warp, the relative 'parts' of their efforts are going to splinter in the Warp and go to their respective patron. 

If you CAN maintain the cohesion of emotion, it typically developts into a minor Warp Entity. Depending on their strength and usefulness, they are then either torn appart by their more powerful counterparts and absorbed, or left to he their own thing. 

They CAN in turn absorb other entities, if they become powerful enough... A entity of Indulgent-Rage could become powerful enough to absorb both Khorne and Slaanesh, but there is no way to merge the two.
