Not sure if this will work the way you want it to. The point was that, originally, the pipeline was part of the installer, but, as many people downloaded and installed later versions of the Virtual Audio Cables program than that which was bundled with BAE, complications arose.
Now, VAC is not automatically installed, but a link is provided pointing to the latest version available from the Breakaway website. You can optionally use the one already on your system, or you can remove that and update to the latest, separate from the BAE install.
Therefore, theoretically, you could use a different device. Provided that BAE sees it as an input/output device, you could use it.
