Is there a list of OTC stocks being added to the major exchanges?
Reuters has a service you can subscribe to that will give you lots of Financial information that is not readily available in common feeds.  One of the things you can find is the listing/delist dates of stocks.  There are tools to build custom reports.  That would be a report you could write.  You can probably get the data for free through their rss feeds and on their website, but the custom reports is a paid feature. FWIW re-listing(listings that have been delisted but return to a status that they can be listed again) is pretty rare.  And I can not think of too many(any actually) penny stocks that have grown to be listed on a major exchange.
