The armor set from Mass Effect 2? I don't know, I thought the open mouth thing looked kinda weird. Don't think it'd fit Halo at all.
...Oh, you mean the hovercraft? Well then, yes, I'd like to see it. UNSC air has always been a bit of a problem for Halo. Halo 3 had the Hornet, which was such a freaking tank that it was never put in any official maps until the Legendary DLC came out with new Hornets that were super nerfed. Halo: Reach had the Falcon, which had no real offensive capabilities whatsoever and was only effective when used with a communicating team, which is uncommon.
Halo 4 just said "Screw it, bring in the Pelican with rockets and lasers!"
The Kestrel is the perfect balance for the Banshee. The Banshee is fast, nimble, but fragile. The Kestrel is of a similar design. So I really hope it's put in the game and well balanced, so we can see more air combat in the game.
But let's be real, we all know what Halo 5 needs: Pelicans and Phantoms.
