I think she's still in the top 5:
Leni
Lucy
Luan
Lola
Lynn
Maybe she fell below Luna by now? But as you said, she was the top dog for a long time, people don't draw or write about these characters as much as they used to, which makes most of the material either lost or really old, so the chances of stumbling upon a Lynn art or fanfic are high.

>Lucy seemed to get more popular later on
What they did to Lucy was a soft version of the treatment they gave Lynn; they completely severed the ties she had with her family and made the mortician club her new identity. The magic stuff had a role, like NSL had a role in Lynn's downfall, but in my opinion the biggest thing they have in common is the writers' efforts in avoiding anything that could be seen as controversial or icky during the post Savino years, any intimate or self growth moment had to be without the whole family for the longest time for some reason. Lynn had to become the rough bully, Lucy the mortician club member.
