Well I decided even though they weren't litterally ment to combine I'd do it anyway. Behold the Hydra Cannon!

The Skyboom Shield and Requiam Blaster are conected by mini-con ports. I'm not sure why but Blastoff actully has a male port on him that stick straight up while combined as a blaster. The tip of the Star Saber is held between the thrusters/legs of Blastoff and surprisingly actully holds there fairly well.
Oh and in case you're wondering, the reason Astroscope doesn't have his missle is because I have no idea where it is, I lost it the same day I got them.
