Variant Racial Class Substitutions for 3.5 e6

[wadledo]

So, I have plans to make a setting wholly for the e6 variant of D&D 3.5, and since I have nothing better to do, I have decided to get back into the crunch of things by making up 5 racial class substitutions for each significant race.

My problems are threefold:
1. What races are significant? The setting is largely open, so there is no particular reason to exclude any one race in particular (with the caveats that there are no non-elemental outsiders or Dragonblooded races). An easy solution would be to only do the Core races first and then moves on through the source books.

2. Some of the races (Gnome, Dwarf, and Halfling) already have 5 Substitutions (Halfling has 6, for some odd reason). I think my best shot is to reprint them where they need a boost and ignore everything Incarnum for now, since it's mostly absolutely terrible. I also desire to make at least 3 Substitutions for subraces. What are good choices for subraces?

3. Not including Oriental Adventurers, or variant classes, or NPC classes, there are 45 published classes in D&D 3.5 that I can find. How do I choose? Some of them are surprisingly obvious (Binder, for example, needs to have a variant for elves, since at least 4 Vestiges are associated with elves in a strong way), and I would like to give each race a Fighter variant, because I see it as an excellent baseline, but where do I go from there? A few variants for the classes from ToB wouldn't be bad, especially as an upgrade to some of the more iconic race/class combinations.

I suppose what I would really love now is some direction. I can do fluff, I can do politics, and I can do plot hooks, but the actual mechanics seem to be eluding me.

I sugest fluffing out this world before giving it such broad reworks of racial substitutions.

if you are willing to accept and work homebrew into this world, then i suggest leveling out the playingfield alot more then just using E6, as E6 is to keep people where the game consists of badasses doing the impossible, but still fun. sure ACFs are nice, but not all of them should be separate ACFs (Im looking at you, Dungeon Crasher and Charging Smite)

Classes like Scout+Ranger should be combined then, to balance out everything. in fact, almost everything Jiriku does is worth looking at, while Kane0 did a bit of work collecting the base classes reworks here.

As I stated quite a few times, I have no problems with fluff. That isn't my problem.

Also, how does e6 not level the playing field already?
