Converting active dry yeast to rapid rise yeast for bread machine

First of all, I hope I do not offend anyone here, for this is a question about bread machines. Bread machine recipes call for rapid rise yeast, however I have an abundance of active dry yeast I would like to use instead.  It was suggested to proof the active yeast in warm water to dissolve, but it clearly states in recipe, not to add the yeast to the water.  It should be added to dry ingredients.  Now I am pretty new to bread making. I read that active yeast has much larger granules than rapid rise. This probably is a crazy question.  Is it possible to put active yeast in a grinder to make the granules smaller, and therefore work for the bread machine?  Would the amount used need to be adjusted as well?
