I've tried it Gandalf. If you do; your main line gets butchered by enemy archers or cavalry (if they have any). You do have to position everything exactly just right and it would work, if the archers moved forward when an area is 'cleared' or safe.

You *can* put a small core of HI in the middle front as far as they go as the archerbait, then put in the top or bottom just a pixel back your archer patrol with another unit behind them for their 'front line' and it works fairly decently; but once your main infantry get forward, they will still get massacared, even if you chaincast Aim on the stupid bastards.
