Count me in for, "No go, bro." It's not a terrible idea in terms of what it could offer, but neither is it spectacular, and it's certainly not feasible. Moreover, it's pretty clear that this strategy wears the OP's biases on its sleeve, which wouldn't necessarily be a bad thing if it wasn't so inherently subjective. In short, I can't help but get the feeling that the OP wants WotC to publish a
PH that caters specifically to his own preferences.
Now, here's an idea to make this workable:
- Start with a "core Player's Handbook", which offers fairly generic race and class archetypes, along with all of 150-ought pages of important rules for the game.
- Rather than publishing additional PHs which would be approximately half-full of reprinted basic rules material, identical among each book, each book could be entirely focused upon its "theme mechanical elements" (new classes, races, feats, powers, items, and rituals).
- Folks could buy the "Psionics Handbook" or "Player's Handbook II" when they wanted to use material from either sourcebook in their game, although only the Core PH would actually be essential to run a game.
Oh wait, that's exactly how WotC is doing it and has been doing it!
