Or just look for Urano Metria on wikipedia to get all 88 constellation.

Anyway, I'd like to see Lucy use her current keys to full capacity, rather than seeing her stuffed with more and more keys. The more keys she has, the less often we will see each individual spirit and there are spirits with barely any screentime in her arsenal already.

Besides, with the Spirits getting stronger as Lucy's power grows, they could also very well get new abilities "unlocked" as well.
