I'm not entirely sure what you mean, aside from the last part.

A comedy series about brickfilmers could be quite funny; that kind of meta humour has been done before (most recently by Walter Benson in the legendarily awesome That's The Way It Goes, and then a while ago I remember something where Hazzat tries to kill Daragh).

The basic idea sounds like a great idea, and the past has shown that other brickfilmers are up to cameo in this kind of thing (though I would always ask before including someone in a script, just in case), but beyond that you haven't really given any details of the series. What's the actual story? What's the context? Why are all these brickfilmers appearing? I think until you can give us a better idea of what the story will be, we can't really help give you feedback.
