Default Kenko KNT20 & TCON-17?

I'm very interested how would this combination work on my Panasonic DMC FZ1. It would add 2.97 to original 12 so I might go after it. I just want your opinion: could this work without strong vignetting?

Here's a picture taken with G2 with similar combination:

So, what we have here is:
58-52mm step-down ring
Kenko KNT20 (or LD20T, the same thing)
67-55mm step-down ring

I'm looking for similar combination:
55-52mm step-down ring
Kenko KNT20
67-55mm step-down ring
Am I right if I say that this combination will have less vignetting? And if I'm right, how much vignetting, do you think is going to have?

Does anyone know any additional info about difference in vignetting between Powershot G2-Panasonic DMC FZ1 or between TCON-17 and B-300?
I hope that I'm not asking sth really stupid again.
