I'm developing Managed Bootstrapper upon Burn to extend the capability and
get more control over it.
I handle already installed Package and Bundle in following two events:
    if (e.Operation == RelatedOperation.Downgrade)
    if (e.Operation == RelatedOperation.MajorUpgrade || e.Operation ==

    if (e.State == PackageState.Present)

Hope this may give you some idea ....
