The purpose of late addition is to reduce carmelization which results in a lighter colored beer.
Subsequently, anything you do (out of the ordinary method) may have 1 or more desired/undesired effect.
With the LA technique you can use fewer bittering hops as long as you keep the malt water ratio about 1:1.
If you use more malt than water the density increases and you have to use more hops.
The same goes in the other direction too, but I believe hops need some malt to aide in bitterness extraction.
