[Warhammer 40k] Has there been or is it possible to have a ship to ship battle within the Warp?

I think the question really is whether there would be any point to it. The answer is: unlikely. The extremely volatile and unpredictable nature of the Warp would not only place both ships in extreme danger, but the fact that most known laws of physics are altered might very well render their weapons utterly useless. If somehow they did manage to get shots of it's entirely possible they'll end up blowing each others gellar fields out and being chewed up by hungry demons. 

In short, no matter how badly you need to catch someone, waiting for them to emerge from the Warp would be the better choice to going in there after them. Immaterium's a fuckery place, yo.
