I think this is not going to work on any large scale. Say you are a domain expert in some tiny little plant on some tiny island. Like, you wrote your PhD thesis on that plant. Sure, this is not very 'big', but it merits inclusion into the Wiki. Telling people that want to contribute, that are the domain experts, that have read and debated all the sources of which they may be the definitive source, that they have to go figure out how to set up their own wiki somewhere and then try to figure how to 'pull' and 'push' things to Wikipedia on a semi-regular basis because of some bot's deletion bias is the best way to make certain that Wikipedia is only written by insane people.
