You guess wrong. Take a closer look at the Flydusense: On the other side you find a square marked as "FreeIMU" for example. The Flydusense provides 3.3V and 5V and straight I²C connection so you can not even put a WMP and BMA or a FreeIMU on it. You can put almost any sensor or IMU on it.
It's obvious that you don't know much about Multiwii, sensors or the Flyduino. That's okay because we all started like that once ago. But do yourself a favor and learn a little about that before you think you know what to improve. Please don't get me wrong: I don't want to blame you in any way, it's just an advice.
And btw: A WMP+BMA connected to a MEGA board like the Flyduino is casting pearls before the swine. But this is only my personal mind.
