Don't think so unless maybe you make a sugar syrup... For what it's worth, I'd go for something less sugar based than a recipe calling for molasses. Honey, almonds, yogurt, all that good stuff. But if you mustn I think the molasses is just to provide the stickiness in the dough. Try honey or a syrup w/1 part sugar to 1 part water, boiled for 5-8 minutes, until quite thick...
Good luck!
