cybertalus: What other deities are you considering? I'm curious now!
Off the top of my head, any deity which has a strong association with animals or natural forces such as the sun, the moon, the wind. So Selûne, Lathander, Shaundakul, Sehanine Moonbow, and Eilistraee immediately spring to mind. I've probably missed a bunch who are from outside the Faerûnian and elven pantheons.
Death is also a part of nature, so I could easily see Kelemvor sponsoring a sect of Druids who focus on the death aspect of the natural cycle. Such Druids would probably be opposed to burying creatures in tombs since this delays the return of their bodies to nourish the earth. In fact they might raid tombs with the intent of giving such creatures a "proper" burial.
Shar, with caverns in her portfolio is a distant possibility as well. Though I'm holding off making that call because I'm considering that the real reason for Lolth's silence was a war with Shar that resulted in one of the two goddesses (haven't decided which one) slaying the other and taking her portfolio and (for the time being) identity. If I go that route, the victor becomes a nature deity anyway, since your original post prompted to decide to give Lolth nature deity status.
I'm also pondering making the elemental lords be nature deities. Each of the four elements they represent is a force of nature, so it makes sense in those terms.
Having more nature deities suits me in a larger sense because I've ditched the notion that all of the nature deities are one big happy family. Chauntea, as the goddess of agriculture has a positive view towards cities and civilization, which often puts her in strong disagreement with Silvanus, who prefers untamed wilderness. Having more nature deities, even if nature isn't their main focus, makes for more players in this coming conflict, especially since most of the existing nature deities are likely to side with Silvanus.
