I wonder if it would make the mixture too rich at mid throttle. My thinking is the lighter spring will allow the slide open a little farther at any given throttle position where the slide is in play thus acting as if there was a slightly larger jet due to the needle being open farther.



I don't see how that could make it richer. At the same time the needle is pulled up, the slide is opening to allow more air. Seems to me that the possibility of surging (or total loss of control) is the only downside.
