is it possible to upgrade the 94 cbr600 f2 headlight design with just the square headlight and upgrade it to a newer version such as the 01 or 02?

If you can, does it have to be custom or is it some thing you can buy and is it expensive?

 

I was also wanting to do this. Anybody have ideas?

 

There are no such kits. However you can "swap" plastics.
