My impression (as being Slav myself and speaking Serbian/Croatian as a mother tongue, and a bit of Russian that I've learned in school) is that Slavs can understand each others fairly well when everyone is simply just speaking in their own language. I really see no point in making the artificial language, as while understanding it is probably not hard, learning a language like this would be super hard because of how close, but still different it is to the existing languages. So you end up with a language that everyone understands, but no one is able to speak it...
