Allow Seeker of the Sun miqo'te to have longer fangs

[aceeko]

I would only be okay with it if we also got access to the slit cat eyes. Each clan has 1 unique cat thing they offer, Keepers have fangs and Seekers have the eyes. Seekers are already more popular due to the slit kitty eyes.

If you read the original post, it is clearly stating that Keepers also have a "unique cat thing" for themselves, which is having dilated eyes.

1. The main visual distinction between both groups is found in the eyes because of the amount of light they are exposed to: more for Seekers, less for Keepers.

So, the difference between the cat's eye being slit or dilated depends on the amount of light they are exposed to, therefore, they are both unique features for each subrace.
By giving Keepers slit eyes, you would not really be trading anything, you'd be giving them "more" options and there would be no distinction whatsoever between them and Seekers.
