Should I use a Pawn?

I have an idea for a robotic player character where the bottom half (legs portion) separates from the top (head portion) and flies to the top of the level and performs attacks while at the top of the screen. Kind of like the game “R-type” where the ship has an orb in front of it that can be shot out and comes back. Would I use a pawn for the legs of my robot with the head being the character and import them in as two pieces? Are there any good resources I can refer to on this? Thanks in advance!
