File Store Provider

I have been looking into a way to generate a rule that allows storage of the native file, web-viewable, and an alternate file. Now by default the alt. file will be stored in the weblayout dir. What I would like to do is store that alt file into a database table. So here it is currently;
Native file stored as blob in UCM tables (Current)
Web_viewable stored in the weblayout dir (Current)



Alternate XML file stored in an alternate db as blob for backup purposes. (looking to accomplish this)

If anyone knows if this has been done please share!
