I think if I did it, I would want the aperture control. I can get everything I need from work...
Either that, or just converting it over to the EF mount... Now I'm not sure, lol.
EDIT
Wow, I didn't know it was so easy...

...About to go try that right now.

Damnit. Apparently, on the kit lens it's a little more involved than that... The piece doesn't just pop out... I'm going to have to cut it out.
...Too late to turn back now - I already broke it.

Well, I guess the kit lens can go back in my bag now.
Successfully converted to the EF mount.

Everything still works, and it fits great.
There is heavy vignetting at 24mm, and you can see the sides of the image circle at 18mm.
I have to say that it was very easy... The rear element sticks out a little at 18mm, but I'm using a 1N RS so I'm not worried about it. The mirror doesn't move, so there's no way for anything to get damaged. Any other camera, and I think I would be scared to fire off a shot at 18mm...
Sorry for the hi-jack.
EDIT
I merged all of my posts to make the hi-jack less noticeable, lol.
