Why would I do that? Only the thing they have issue with would need to be changed, it wouldn't take any longer than another way of doing it.

You seem to have forgotten what I said, something needs to exist for me to work with. Well, in this "stakeholders want something changed", something exists. It's not a rewrite from scratch.
