I was thinking of doing the same and wearing it on a 20 motif! I did not think of making it a lariat. My problem is I am a WG person, so my choice is only the panda which is why I have not purchased.
I love the owl (big eyeballs), the cat is next (I love cats), then the duck (color pops), and then the rabbit (really cute as he is showing his fuzzy little butt).
I had thought hard about getting the panda, I tried it on at the boutique, it clips fine to the chain, and it was cute. The panda is not my favorite animal, and because he is just black & white, it did not add much to the 20 motif WG MOP. I was hoping to add a fun pop of color to the 20. But, as you said, I was also not sure how often I would wear it.
I would love to see some photos of your non-VCA clip worn as a lariat. Great idea!
