I guess no one knows how to mod this mysterious game.
Would devs consider adding a such an option to the game? One reason I'm back playing MAN instead of Domination now is that I think the unique units in Domination are just not well balanced. This is really a shame considering all the improvements made in Domination, including a better (though still not completely consistent) system of initial disclosures that lessens the PL advantage. A mod or option to have all units available to both sides would allow those who think as I do to play each other on equal footing, while still leaving anyone who desires free to play with the unique units remaining unique. Options like this are bound to make more customers happy.
That said, such an option could introduce problems into any future ranking system, because FNU would be at much less of a disadvantage (though still a small disadvantage) if it were able to purchase all the same units as PL. Thus, anyone who wins games as FNU where the unique units are maintained as unique would have accomplished a significantly more difficult task.
