It would really have to be a joint effort and have sustained support for the character to really take hold and get wide use.

When DAZ releases a new character, they already have numerous poses, clothes, skins, etc ready for them at the same time.

There are independent models out now....

But it usually falls on the character's creator to make most of  the content. Whereas Vicki4 has a constant stream of content released daily.

The totally free original characters usually have a beta lifespan and newbie users have to know which version works with which morphs and which new uv map, etc... a lot of newbies may have a hard time using free original content that's always in a kind of beta status.

The great minds of this community could do it though.
