Swap: CPL filter, 67mm for 62mm

Have a Kenko 67mm Circular polarising filter, purchased a when I still had the 16-45mm, but now I don't have it anymore and none of my lenses are that big, and doesn't look like I'll be getting any in the near future.
Wondering if anyone has a similar 62mm CPL that'd be happy to do a swap?
Doesn't have to be Kenko, but wouldn't want it to be a random ebay generic one.
Thank you

P.S. I'm away climbing this weekend, so if I don't reply, I'm alive (hopefully) somewhere in the South and will reply when I get back on Monday

Have you thought about a step-up ring? They're cheap, if you can't find anyone that wants to swap the filter.
Something like this;

as the man says : keep the big one ! you may need it later

step-up rings +1 ^^

Oh,forgot about them! thanks for the reminder, shall do that then
