I have to say that the pricing of magic is soooooooo far askew. There should never be a way for a person to make a character that starts with a +2 long sword and still have enough money to buy armor and equipment. Furthermore, if that is the price for a +2 item, how much are you giving away +1 items for. Why would anyone ever need to take feats and training if they can simply run down the street and buy a few magic items to make up the difference with absolutely no training whatsoever.
That being said, I understand the problems that you are having in building a version of D&D that will suite both the classic players as well as those who like the newer versions. I would like to make a proposal and say that you bring back box sets for game worlds. Consider a spectrum of prime material planes infinitely arrayed with different variations of magic. Thus the people that like the Monty Python hack and slash campaigns can have a world that has more magic, greater stats and so on. (Ex. Ravenloft and Birthright) The role players could play in worlds that would have moderate magic and stats but a grand fleshing of storyline, background and roleplayability. (Ex. Forgotten Realms and Greyhawk) You could even have a couple of specialty realms for extremes. (Ex. Dark Sun, Planescape and Spell Jammer) Considering the infinite prime material planes it would be easy to say that characters are prohibited from finding their way into the other individual realms and even those who have the power to do so will just shift through the infinite realms similar to their home plane. In short, the god character players will never meet the characters from weaker realms. Player builds could differ from realm to realm, as could gods and demigods.
