Question Can I flash Google Search to my phone even if it's not compatible?

On my Droid 3, I recently flashed the Google Now zip and followed the instructions on this site. It has been working great so far.

I noticed that the zip itself matches the folder hierarchy of the phone system folders. Am I correct in understanding that if I were to replace the Velvet.apk with the newest version of Google Search (after renaming it properly) that if I flashed this new zip, it would give me the updated Google Search/Google Now?
