No, because that won't change the number of heads that are present to service the IO requests, nor to segregate requests effectively. Your primary goals should be to reduce IO (investigate using LVM backed VMs instead of file-backed) or to increase hardware resources (possibly a larger number of smaller disks if SSDs are not in budget).
