Well, H.G.M., if you are believing in your value model, and your engine is using it, then this engine will avoid valid trades (as I regard them to be). If you would trust in your model, you could easily add a black Knight and remove some white Pawns and still have a value sum 'advantage' of the white Archbishops' team. So why do you not test these arrays?
The arrays as I have tested with SMIRF have had an advantage for White of 3.1296 in my model.
In your model (normalized to a Pawn = 1) the advantage has been about 12.944 (more than a Queen's value).
P.S.: Why not have some test games between SMIRF using Black having 9 Knights against your program having 4 Archbishops, each having 10 Pawns? In your value model it should be nearly impossible for Black to gain any victory at all.
P.P.S.: The game as proposed is no subject for Blitz, because it is decided by deep positional effects. So I used 60 min / game + 30 sec / move for the time frame, which is important.
