You can't install the same MSI twice, but it looks like you need your MSI organized into two features, one for each driver. At install time the user can chose to install one or both drivers. When they go into maintenance mode (by running the same MSI or from Programs/Features) it will show the installed features and allow the user to add the other feature. So yes, you need to change maintenance node to offer feature dialogs, and that will need two features in your MSI as described.
