Tailsitter Planes with unusual configuration

Hello Ardupilot community,

I am a beginner with Ardupilot.
I am developing a tailsitter with the following configuration:

> 1 front propeller

During vertical take-off

turbines 1&2 : for torque control → to balance the torque induced by the propeller
turbines 3-4 : for yaw control
pitch control: with Elevon

During horizontal flight

turbines 1,2,3,4 are off, just propeller & elevon are active.

Landing:

Parachute

My question is about the best type of standard configuration I should use and how to adapt it to obtain my own configuration:

Best type of standard configuration I should use:
I started with a Tailsitter Plane, the basic configuration. It feels natural but maybe a more experienced person will recommend something else ?

How to adapt it to obtain my own configuration:
I need to add turbines 1,2,3,4 and make the controller understand that during vertical take off, it has to use them to control the airplane. Do I have to adapt the code of the firmware and make my own ?
if yes how ?

Any help is really welcome !
Thank you very much !
