Aftermarket projector headlights are definitely not designed for HID's. I agree with your friend 100%. That would be a bad idea!!!!!! The beam pattern would suck like a desperate prostitute and your housing might not be able to handle the heat.
Most of the guys on here will tell you that if you have a Gen 5, you should do a hid retrofit.
