Yes, that would work. Viability and dosage control will likely be an issue, but blue is a vigorous mold.
Another way to propogate blue penicillum mold is to do it the way they originally did in France Take a thin slice of bread and put it in the same bag as a slice of blue cheese, letting the cheese touch the bread. Soon, the bread will get moldy. Take the bread, dry it out, make it into crumbs, and sprinkle the crumbs as the middle layer or incorporate into the evening+morning curd (for roquefort), or just curd.
