In the TRUEST sense of the word, it could be published, but the questions is, would anyone want to purchase it?
The information I have could easily been written up, (most of it is) and transfered to a publishable format. However, the lack of certain 'elements' that are staples of 3.5 like PrCs and treasure tables and mega magic, would proabaly deflate the sell value. Its a low tech, medium magic world with lots of intrigue and world spanning events.
Whether or not the players characters participate in any of those events is complelety optional. Goblinoids are extremely rare and orcs are actually civilized. Reptilians however are a plague on the butt of humanity and their allied races. Contact with outsiders is almost unheard of and gods rarely if ever directly intervene. Its more historically accurate and for some, the emphasis on role-playing vice 'roll'-playing might be a bit of a turn-off. Is it possible, yes, but not very liekely.
