Unfortunately (although a nice idea) with such an army played to the extreme you really have to hide your three or four units of knights behind and have to hope they won't get attacked (which could even be fuelling the constant opponent's mockery about the cowardly knights

). And it will be very risky to use your knights for the urgent needed punch.
The minimum breakpoint I would aim for is 3 (so at least 5 units of knights, better 6). I would then form three brigades of two units (so that your breakpoint is not cracked in one easy sweep). But Guthwine is right, keep an eye on those flying knight-killers (even weak units can kill you when coming from the flank). And with those three brigades you have a little punch when needed.
That should still give you some points for some commoners.
I would not aim at that army list when beginning Bretonnians but such an army can be fun to play as a variant once in a while.
