Neutrality fails for most mercenary corporations in such a small sector that is Sirius.
Yes single ships can work sides etc but entire corporations aren't.
They rely on their reputation for work and if it is damaged, it can severely hampen any hope they have of being hired anywhere.
You take work in Bretonia, Kusari won't like you.

You take work for The Order, BHG and Liberty won't like you.
You take work for Gallia Royalists, Council and Sirius won't like you.

The main point is that no one is desperate enough to hire on people.
Warfare in Freelancer is frankly silly. You can fly through every system of your enemies, encounter plenty of enemies and still get away without a scratch.
It is very easy to go it alone, to put it simply. I have a few too many rogue characters but they all are perfectly safe, simply because it's too easy to avoid fighting sometimes.
In the end, S&D gets most of the work there is nowadays. A new group that plans of working every side will not have a good reputation to start with, let alone after a job or two.
There are just no groups in Sirius who really NEED any help, let alone help they pay for.
Overall, I would say this will not work. Good job on the proposal though.
