Fructose is not glucose (obviously) so sure, changing to a sweetener with more fructose and less glucose is going to reduce your blood glucose measurement.

However, the fructose has to be processed by your liver, just like alcohol. And too much can lead to fatty liver disease, just like alcohol, and all of the problems that come from that. So eliminating sweeteners in general (if you already have metabolic disorder) is going to be a better choice than switching from one to another.
