[Q] How to modify a notification

[ra9b]

I have been looking for something that will allow me to edit what my notifications say for privacy from nosy people. I found an app that was called "hide my text - invisible." This app was great for people who use their native SMS app for sending text messages. It allowed me to make my own notification if i receive a text from a certain person. Usually, the notification will scroll the contact's name, and some of the text. This app let me change the notification ticker, text, and the icon, so that if I got a text from a contact, I could change the ticker to read "unread emails." This app is great, however it doesn't work for 3rd party messaging apps, like google voice and text free. I do not have a messaging plan, so I have to use these 3rd party messaging apps. Is there any app, script, or mod that will allow me to have the same exact features of the "hide my text - invisible" app for my 3rd party apps?
My phone is rooted
I have a HTC Droid Incredible
It has a Jelly Bean Rom on it

Any help?
