I have a lot of my rods modified, from Walmart specials right up to $illy expen$ive ones, the mod you are contemplating will work well, have it done from the butt, don't let anyone talk you into stripping that blank. Everyone loves to talk theory, I fish with what feels right, I don't care what the specs or #s say. Also keep in mind that different jerkbaits fish best with different actions/powers.
