* Don't restrict it to ONE planet,
I see nothing wrong with fleshing out a base of operations, spending some time worldbuilding. I'd much rather have an all new planet than Tatooine again.
* don't give me TWO Jedi (when, according to the first SW film, "their fire has gone out of the universe")
Technically, neither of them are Jedi. The kid is just starting and Kanan was only a Padawan when the hammer dropped.
* don't give me characters with zero characterization
So how much of the show have you seen? Because they've been fleshing out the characters for a while now. I would much rather have development in dribs and drabs than one massive exposition episode.
* don't give me constant slapstick
You mean like R2's pratfalls, 3PO acting like a goof and Yoda being "wacky".
* and please DO give me some interesting stories.
Obviously the show isn't working for you. I think the first season of Rebels is WAY stronger than the first season (and premiere movie) of Clone Wars. Clone Wars was pretty good at the end. . . but really godaweful when it started.
I really think its too early to start thinking about Rebels based sourcebooks. I would wait until the end of season two or maybe even three see if the show has enough material not available elsewhere to justify a coursebook.
How so? The show is out, people are excited about it, if people want to experience things in the series now, why wait?
Look at how many ship, vehicle, and weapon models plus planets appear in a typical FFG StarWars sourcebook and how many have appeared in Rebels so far. Now remove all of the items which have appeared in official FFG books and I don't see much left.
Although to be fair, in electronic form it's easy enough to add more pages for seasons 2 and 3. . . .
