Yeah, the Crawlers or even Rebel Yells might work well here. If you want a ceramic bridge pickup, the Cold Sweat would be a good choice, but for those bands .... mmm, I'd plunk for Alnico. Crawlers can get you a good Slashy tone, and are good for Whitesnake I'd say. Cranked up, they'd handle a decent metalish tone for Ozzy songs, I think.
