I do not understand. A bootstrapper exe does not run msi custom actions.
Not sure how one relates to the other.

The custom action dll _must_ exist in the Binary table for the other custom
actions to work. The rows for the other custom actions in the CustomAction
table will reference a row from the Binary table. Theoretically your new
CustomAction element would just need to use the same binary *but* you still
need the Product element to reference the new CustomAction element. That
can only happen if the Product element was authored to allow extensibility.

There's a lot about your project that doesn't make a lot of sense to me,
likely because I don't completely understand it yet. Beginning with the
projects you have and how they integrate with this NuGet package would be
