I think that's expecting way too much.
Personally, I'm against a forum completely dedicated to VN creation because it would have very few activity, and it'd be just another green dot that calls attention. I think it's better to just use a thread instead.
But there are tons of VNs considered good that have bad artwork, no voice and sometimes little to no CGs. Things that actually make success, like Nasuverse stuff, that have no voice and have "bad" artwork. They are still awesome anyway. There's also things like Higurashi, Umineko or Higanbana, all having no CG at all, no voice and definitely bad artwork, and they're still a few of the best VNs I read.
Things don't need nor should need to be perfect. And as someone who reasonably knows japanese (enough to read without needing a translator) and read a lot of VNs already, I think putting interest in that part of the community is not really needed. The western jp reading community is reasonably small, and you don't need to force yourself to put interest in them.
Say that you make a VN- You post it into the community, get a few friends that are into anime to play it and tell them to publish it if they like. Only that by itself is already greatly contributing to Fuwanovel's goal of making VNs popular in the west.
