hotchkis leaf springs sitting too low :(

I guess these are the brackets from mancini, doesn't seem to be the solution, It lowers it about an inch. http://chucker54.stores.yahoo.net/mabospha.html

Are there any drawbacks to adding a full size leaf to the leaf stack?
just wondering how hard it is to do, Is it possible to re-use one of the leafs from my old springs? I just hate messing with something that was engineered for a specific purpose LOL.
