Prevent Trebuchet from showing up in Recent Apps?

Here's the setup I have for my phone right now: - I am running on a custom ROM that has Trebuchet for the home application. - The custom ROM is ICS-based. - I have somewhat successfully gotten Google Now (the Jelly Bean feature) to work on my phone. - I decided to use Home2 Shortcut to map double-clicking on my home button to launch Google Now's voice input. The above setup works fine aside from a single caveat. When I view the Recent Apps menu while inside another application, I can see Trebuchet on the list. This is not the behavior I was looking for and from what I can tell, it is appearing on the Recent Apps because I've set Home2 Shortcut as my new home app (to handle the double-clicks) and then Home2 Shortcut opens Trebuchet as regular application. So yeah, now I want to know how I can make Trebuchet **not** appear on Recent Apps. Is there some kind of manifest-editing that I can do to make Trebuchet act that way? If not, what other approaches can I try?
