That'll work, but you could just as easily simply add the document. Solr will take care of deleting any other documents with the same <uniqueKey> as a document being added automatically.
Optimizing once a day is reasonable, but note that about all you're doing here is reclaiming some space. So if you only do a few deletes a day (by a few I'm thinking several thousand), you may be able to reduce that to once a week. But there's no particular reason to make it less frequent if you're satisfied with how it works now.
