I've tried the 50/50 split with Conjecture - how successful, I guess, is something we'll have to see. (Only one GoH, so there can't be balance there, but the FGoHs are definitely media fans, and I've tried to add one dedicated media event per dedicated lit event). But the issue remains somewhat more complex, and it is why I don't think we can be that successful at a combined con, unless it is very big. We have to appeal to at least four groups, not two. Established fandom, new fans, media fans and lit fans. That makes a 4 way split, and while you'll get some crossover, it is hard to see how any one group could be entirely satisfied with the programming in a smaller con. You can get close (it isn't a lost cause), but it will tend to be tricky.
