It would be an order of magnitude simpler to create a transform containing your new feature and its associated components.

Have you downloaded the MSI SDK ? There are MANY example vbscripts in it which can be used as a basis for what you are trying to do, including a couple of VBScripts which you could use from a batch file to edit your MSI tables.
Post a bit more information on what you are trying to achieve and maybe some more relevant answers can be provided.
Are you trying to edit your MSI tables during installation? I've found that a handy solution to some issues.
