I seriously doubt there is anything you can do to make Google crawl faster than planned. Maybe temporarily if you change your sitemap; not permanently. But you may be able to make them crawl slower.
g will ignore the "Crawl-Delay" line in robots.txt. (They say so explicitly in gwt.) But other robots may honor it.
