Frame type with central motor and peripheral motors - is it supported?

[Andrew_D (Andrew)]

Does Arducopter support a quadcopter or a tricopter with additional motor (fifth or fourth) positioned centrally? The central motor provides majority of lift while the peripheral motors just stability.
If so, what versions support such frame?
