If you can code something no matter how, then you can probably include it in the available event handlers. You have the ability to run just about anything you want and vb scripting will probably provide the simplest ways of doing so through the internal event handlers built in to SSIS

Phil identified exactly what I was tactfully avoiding saying in that you seem to have dived in without knowing what the tool set actually offers. I see this time and time again and while many a time this can result in a reasonably elegant solution it is in fact a re-invention of the wheel and I am not convinced that employers will see this as best use of ones time.

The SQL Server tool set is complex and as you say there are a myriad number of ways to solve a problem but generally there is always a best technical solution to address a problem rather than a technical solution looking for a problem to solve.

The only way you can provide best technical solutions to a problem is by a very detailed knowledge of the tool set and hence the best way to solve any specific problem.
