Yes, you can do it. I did it on my lexus GS. But I highly recommend to buy a harness or use hid kit so you don't fry your elictrical wires

H7 and H3 will have a different focal length, that is if your kits maintain proper focal length. Your beam will be seriously affected. Not to mention that HID in fog lights are not a great idea anyway. Basically, you will not be able to use them as fog lights.
