That's not going to work. It won't do anything at all. Google crawls at its own rate and it does so depending on how frequently there is new content to index.
Honestly, sitemaps have become almost obsolete. It is helpful once for a new site (you can submit one through Google Search Console actually) to let Google know you exist. After that, Google will find you and once it finds you it will check back periodically at its own rate.
