I know my 500g Brooks pro saddle was very noticeable over a lighter one. The pendulum effect can be felt.
"
as long as the added weight kept the same general balance." moving that much weight from seat post to bottom bracket changes the balance quite a bit.
My suggestion, following your premise about component weight, does not change the balance.
Also, just to be clear, I don't doubt at all that a heavier saddle is "noticeable" to you. I do doubt that the extra weight on the saddle as opposed to the frame makes a difference in speed, or in handling.
