Should the BBC do a sign language channel?

I think the BBC should do a sign language channel on their TV network. After all Wales, and Scotland have channels. Plus there is a BBC Alban and S4C channel for Scots Gaelic and Welsh language viewers.
Over 100,000 British people can communicate in British sign language.
It would be great to have movies, cartoons, interview shows, news shows, documentaries, and comedies and thrillers made specifically by and for people who use sign language.
Obviously this would be a TV channel.
